THE RANGER
All I have to say is traps are annoying and unnecessary. They make humans cry so many tears that we wish we were dead.
Step 1: WTFTRAPPAWNED but you break free with a mighty "ARGH" and the Ranger runs off to hide. He comes back while you are tanking 6 mighty mobs of elite ownage and he hits you. You turn around and lift your mighty sword and four-five shot him and lop off his head. The Ranger comes back with a Necromancer. When he realizes that was the most idiotic thing he has done he comes back with a Barbarian and they triple finish you (It's Super Effective!)
Step 2: Ranger spawn camps you for by hitting you as soon as you spawn so your regen is broken for 30 minutes until you log-off and cancel your subscription
THE ASSASSINNow, the Assassin is probably the most under-looked class. This may be because it's broken! But, alas, I have different beliefs about the Assassin. I figure when you're level 20 and a level 80 Assassin attacks you, your chances are a little less slim. That's okay, you still have a 70% chance of winning the fight standing still with your hands tied behind your back only using Rest. The Assassin is a special case compared to the rest. You COULD compare the Assassin to the Necromancer but alas! The Necromancer is a ranged caster class so you cannot! However, you can compare the damage mitigation because it seems more like the Assassin is wearing a thin layer of skin for his armour. Now, here's what you want to do against the Assassin:
Step 1: Look him in the eye and used your most broken skill/feat that you decided to put points into not knowing it was broken. The Assassin should now be at less than half health, perhaps even a quarter. When I was testing out a Bear Shaman I decided to cast a heal on the Assassin. The Assassin died shortly afterwards and I laughed and sat on his body. This is perhaps the best way to take out an Assassin. But, there are other ways! Make sure you never 'waste' your most powerful skill on the Assassin because this is considered wasteful and unrequired. Not only will you get an auto-fatality but you will have put your best skill on cooldown and wasted Stamina/Mana. Honestly, I do not even need to make a write-up on how to kill an Assassin as any deaf/blind/disabled person can defeat one.
Step 2: Unrequired, he'll quit eventually.
Proposed amendment: After initial sneak attack by assassin (which may or may not have scratched your armor or snagged your robes) do the following:
1a. If Melee class: Turn, look at the assassin and give him / her your best war face. This should immediately take the assassin to half health. Hit once without using a cool down. Turn and walk away. They will die from the back draft.
1b. If mana burner: Root in place.. walk away calmly. Toast to a crisp at a safe distance. Or, if preferred, simply bake to a delicate crunch.
(Follow these steps, they are more effective.)
THE BEAR SHAMAN
The Bear Shaman is honestly the class that makes me want to yell "PISS-OFF" the most. No matter how much damage you deal to it, it'll always live. You may as well just refer to the escape methods above in the Barbarian section. Known for their SUPER IMBA TANK skills and 1337 HEALS the Bear Shaman will NEVER die. It upsets me, to be honest.
Step 1: Don't bother fighting back, flee to the nearest water source or instance jump. This is the most grand method and works the greatest. I would advise instance jumping because the Bear Shaman is fairly annoying and will most likely water camp you. Talk in guild chat and advise your guild of the Bear Shaman camping you and they will come, however, if you're stuck in the water and don't have a baddie guild. If they say they are busy I would recommend using '/guild leave' Don't ask what it does, just do it.
Step 2: Cry for a nerf on the forums. I know I will.
THE PRIEST OF MITRA
I scream, you scream, we all scream for non-stop AoE and CC. Oh wait, NO WE DON'T! At least I don't. The PoM is known for his/her ability to go around the forums and OOC claiming that they are not over-powered and know how to play their class. This is false and you should ignore all their senseless posts and recommend them to a psychoanalyst. Everytime I see a PoM AoEing 10 mobs at once I 'Exit Game' and realize how crappy my class is. Please ignore the Priest of Mitra Aquilonian under my name, that is false. I am actually a Necromancer and I am fairly bad. When I see priest classes dealing more damage than me I /emote burning and just... I wish I didn't roll Necro, you know?
Step 1: If the PoM gets the jump on you, run and 'Hide' They may be amazing but they are really squishy if you can perma-stun them and CC the crap out of them. Now, the PoM is searching for you, move closer to him while still keeping out of his line-of-sight. Jump him, totally rock him and when he starts casting 'Repulse' (which they all do) throw out your first stun because after 'Repulse' he will be using a Word of Life or whatever it is called. Don't ask me, I don't play one. He'll get up and try and heal and I would advise using a knockback or a fear if you have one. I know not all of the classes out there have a CC option so you may as well not even try and counter-gank if you don't have one. Chances are, if you keep them stunned, they will lose.
Step 2: Attempt to spoil their regen and spawn-camp them because they aggravate you and you want them to feel vengeance for trying to gank.
THE TEMPEST OF SET
I honestly have no clue how to deal with this class. They always surprise me with their casting times and the fact that they can aim their CC and it's AoE. I'd assume that to deal with them you could use the same method as you used on that filthy PoM that ganked you.
Step 1: This is a heavy nuker class. I want you to run circles around them and make it so they can get off as little attacks as possible. One time I was hit with some Lightning and I just imploded. It was not funny, AT ALL! I just vanished and he laughed like this was common. Is it common? I don't know! Anyways, circle strafe around the ToS only stopping to use some knock backs or stuns. Use as much white damage as possible and ignore those long time-wasters that you call a 'combo' I DON'T CARE IF YOU'RE A CASTER! CIRCLE STRAFE AND SMACK HIM WITH A WAND OR THROW PIXIE DUST ON HIM! God! The people I have to work with making this guide! I believe that a ToS is a little harder to deal with on a 1v1 compared to a PoM because of their instant heal and invulnerability. After this dance he should be purty much dead.
Step 2: Start a petition about ToS and go on the forums under their class section and just basically post a screen shot of the ToS lying on the ground and you sitting on his/her face. Then message me and I can go in the thread and have a good laugh for an hour. Then track him down in real life and plant a bear trap in his bathroom. While he/her is trapped, set their house on fire. (Not advised)
THE GUARDIAN
This is the 'Iron Wall' class, you can hit them but they can't hit back. Well, they can, but it'll do 2 damage. You can out-potion that pretty hard-core like. Anyways, they're pretty baddie now, I guess Funcom decided to make them tanks.
Step 1. The mighty Guardian charges you and opens up with an Overreach, which may as well be a back-scratcher now. You swat at him like a mighty fly swatter coming down to meet it's poor, innocent, victim. He takes 1 damage and hits you for 1-10. You use a potion and laugh at the Guardian as he attempts to out-DPS your potion. Hell, he can barely out-DPS your food and that's out-of-combat regen. The Guardian cries and wonders why he lacks so much DPS. He pulls out a Pole-Arm and pretends like he's a Barbarian and circle strafes you while you're tanking 5 mobs that are 3-4 levels higher than you. He pops Frenzy and you turn around, 3-shot him, and walk away with a giggle-snort held in your nose. Victory is yours.
Step 2. Guardian cancels subscription, thus giving you the victory.
