i realize that the troops looks different when they upgrade.why not heros too.making it look more exotic.
Hero skins would be a really cool addition. Like, having to unlock achievements for specific heroes.
i.e. Break 1,000 walls with XXXXX Hero to unlock "This" Skin! - or
Kill 100,000 troops with XXXXX Hero to unlock "This" Skin!
A cool suggestion for the Executioner in my opinion is when you MAX him out in levels, his weapon changes colour to GOLD. I think that would be cool
I have been thinking our Heroes that serve us in the Arena should get some kind of decorative upgrade such as medals they wear or something. Say my team gets me to the 300's like it has this morning. Then just those Heroes used in that team of 5 would get the 300+ medal, and there could be medals at different intervals or they can just go with the HB an hour divisions already in place for the medals.
