In casual PvE, Add-Ons make life more convenient. In PvP they can decide the outcome of a fight. In raids they are a must for 98% of all guilds if they want to succeed. I recommend that all raiders have CT Raid Assist prior to any raid. You can raid using just the in game raid bar mods but the full Raid Assist package is much more than just raid bars. Interupt casting, emergency monitor, res monitor, buff/debuff viewing ect.. are all extremely useful.

Recommended Add-Ons:
