[Drakaris]

If you want a melee, you should probably go Rogue - easy epic, good variety of gear, most reliable snares in the game and great on the raid scene.

If you want a caster, definitely an assling druid or humie wiz.

Also, do not underestimate the value of a skilled battle-cleric in pvp, you will keep people alive and completely destroy the opposition in group pvp by doing so.
