Wizards have been fine for groups since NoS upgrades (around mage DPS).. but wizards bring port and evac (never use them).. mages can CoTH (not alot of use), mod rods, DS, pet emergancy tank.. so just better value (in groups). In raids, a perfect wizard, hand played, with all the ADPS.. maybe top 5, def top 10.. automated, meh, top 20..
Thats "Live" status... with Beta changes, hand played top 5 is pretty easy, top 10 is me playing drunk, so def improvements. I have not had a chance (obviously) to test automated, but i think they will move up, maybe not automated top 5, but better then now, and miles ahead of ToV/CoV..
