My main on WoW is a lock.. dps/damage.. I was a hardcore endgame raider.
I'd like to know what characters are mostly needed so I don't choose one thats overplayed.
As dps in wow its harder to run dungeons/raids because there are so many.
Tanks being the most sought after.. is this true in FFXI? I've played all the rolls in wow on my other toons so i'm comfortable and familiar with running raids.. I want to be prepared for endgame content.

Any suggestions?
Thanks!
