Armor

I really love this game buuuut the ronin is the ONLY guy were u can upgrade his armor you should be able to upgrade all the heros armor so the have a way better chance. And also I want to say that upgrades cost way to much and the extra abillity slot cost ALOT of money,100 gems for only ONE extra abillity I would see maybe 50 gems but not a 100 so ya the upgrades cost to much and you should be able to upgrade all the heros armor
