The current art style is fine. I'd rather you focus on stuff like World Bosses, we've not had one in forever.
This may go off-topic but when will you guys release new characters? Unlocked at lvl 4000/5000 or something like that.
It's usually about a week after I've bought the last one, frustrating the hell out of me and giving me something to aim for for the next 6 months!!!
We will not be moving ahead with the character art change at this time. I don't have an ETA, but I have been reminding the developers that we should probably release them at some point.
