Real Talk.
If you are going to make a caster, make a wizard.
Wizard epic is attainable for any decent guild you join now, and in pvp it is amazing.
Druids are a joke as long as you carry a pumice. Mages cant do shit, necros are a joke unless you are AFK.
Even with Velious gear giving tons of resists and HP, you can still nuke someone for 500 damage that can't be resisted, and you don't have to be near them, or even see them, so IMO Wizards will always be viable and the only caster class to consider for pvp.
