Stay Away - Terrible Devs - Gross Imbalance. This is a clear case of fix it till it's broken. Every update is worse than the one before and new toons are grossly OP until the devs "rebalance" which is nothing of the kind. After 4 years of playing I have little or no advantage over newcomers unless you constantly spend $$ and even then it's like buying lotto. All upgrades, Heros, abilities - everything is chance now. Might as well download a slot machine game. Zero skill or thought.
