I personally don’t get it
As far as I can tell from what I am played since launch, the concept is: “lame wizard trying to be cool”. I am not joking, I didn’t get why so many wizards skills and runes works so bad or simply don’t worth the slot. I didn’t get why wizards has by far the worst sets of all classes (and I played them all). I didn’t get why so many spells and items (like now old “Etched Sigil” in the upcoming patch) gets removed from the game once they started to be good.
Other classes seem to has more reasonable class concepts, seems to evolve more logically.
I think I will leave the game for longer this time -_-
