Wizards are completely generic. Everything that made mages cool in dnd was tossed. They're now like wow's mages - generic dps (and a web... so what?). Gone are:
- spell combinations, like cast cloudkill and send in skeletons
- protection spells, layers of defense and dispelling spells.. forget mage duels
- spells that mages now don't have: invisibility, teleportation, summons, enchanted weapon creation, divination school spells, necromancy, actually it'll go faster if I just say this - almost all spell schools are gone.
The new mage spell schools: fireball school and web school. // HAH! Have you played the Beta? Oh, and if you have, these are the ONLY spells you pick? No imagination?
And they do have some (an extremely small amount of) interesting spells, but they're nipped in the bud by their uselessness, due to PoE's lack of prebuffs, fights speed, recovery times and AI that doesn't target intelligently.
