There is just Waaaaay too much reliance on and pushing of IAP (In App Purchases). Win a match see an ad for another game, lose a match, look at another in game ad pop up for a completely different game. About to go into a match? Click here to buy 3$ worth of temporary boosts that as far as I know dont even last an entire game. Need gold or gems to buy heroes? Oh and check out the ad bar across the top when not in a match. Buy it with real money. Not to mention the AI is terrible.
The game has a unique idea in that you can control 3 champs but they just want you to use IAP too much.
