@up Im sorry if it seems like "bad feedback" but wizards are very bad at the moment. If you want i can remove the post. But if u look at the pictures it will open ur mind xd
Just tested you example. I guess you was comparing Nowii with yourself. Indeed, his dps looks very strong, 2300~(at my tests) vs your dps of 1600. However, lets look closer. Compared your strike DPS and AOE DPS, I see wizard doing more damage, so weapon is the reason. Lets compare your weapons:
You see an legendary thaian sword of rending [+90 damage] (+10) (Atk: 258-430, Grade: 5)
VS You see a lunar staff of luck [+8% chance to deal a critical attack(180% damage)] (+2) (Atk: 127-163, Grade: 3)
Pretty much huge difference in weapons are you see. Lets test your DPS with equal weapon now(You see a legendary hailstorm rod of rending [+90 damage] (Atk: 230-297, Grade: 5). Even if you got 19% damage penalty due to wearing high grade, your DPS is average 2100 damage, while his dps is 2300. Indeed, there is still some kind of unbalance, but he is 30 levels higher, using lvl 200 strike spell and level 190 AOE spell(you was level 187 while my test), aswell as he got just 9% damage penalty instead of 19%. Lets add you some levels, to use equal level spells. Your DPS goes up to 2500 at normal state and goes to 3000 while using advanced concentration, while crusader got no attacking state spells.
So! I admitting that there is still a balance issue, as difference in DPS is pretty low, however its not that bad as you said =) Also I havent yet tested survivablity, so its gonna be confirmed aswell. Thinking its more like green dragons issue, just tried to block orc overseer's and 4 of them making more problems than 6 green dragons due to dragons waves which can be dodged.
p.s. yeah, i forgot +10 on his weapon aswell
