Oo, I could've sworn you played S1/S2.. Well I only got my Mage>Wizard up to 175, but as a mage, your spells are pretty cool, Your AOE's are pretty shitty til 100, then you get a good AOE which hits about the size of a GFB. And your single target spells are quite strong, they also have passives some slow, some freeze the target, some deal extra damage, one has a like a 15% chance to crit, that's the only class I've played so far.
& I'm sure preists are useful since you have exura sio as a mage up until you promote til 150, then wizards lose the heal friend spell, and people always need exura sio's lol
