New to EverQuest, but not Tanking, so....

[Troxx]

Boiled down:

Knights have easy on demand aggro and their spellbooks nicely supplement tanking to a point. Sks are user friendly and mobile. Aggro is easy and feign death is amazing. Paladins bring a lot more utility to a group. At high levels paladin heal potential makes possibly the best group tanks in the game for most content. With clarity and catching a few Med ticks, from 59 plus a paladin can average 700-875 healing per minute with a lightning fast heal over time targeting self while tanking. That’s 5-6 extra fungi tunics worth of sustained healing. Neato buffs to share, 90% rez, and cc/stun.

Warriors suffer from no on demand aggro. With good gear choices they can be highly effective even on a budget they always suffer from extreme gear dependence. At high levels they start to hit Demi-god status. Evasive/defensive is wickedly powerful. With good gear they put out solid damage.

If you want to tank the nastiest monsters go warrior. If you plan on mostly grouping, knights fit that bill well.

I have a 60 warrior and 60 paladin. Both are a blast to play but Paladins are more fun in general unless raiding.
