Heroes Charge! It's like Dota 2 but theory only as the characters auto-fight during the PVP. The PVE is mostly auto-fight but each character will have a non-passive spell you can cast strategically. There is a version called DotArena but i think the Heroes Charge is a HD and Upgraded version with better features. If you guys want a great mobile game which is growing rapidly be sure to look into it.
I agree, With the anonymity of the internet people think its O.K to hack, cheat and disrespect. Too bad about your game and those people who didn't cheat. New rules seem like the only fair way.
