Incredibly rigged pay 2 win system forcing players to buy for money, chests (like the chest system is too rigged) and the medals to buy those chests, and inconsistent add rewards for medals and cash like seriously those adds can take a full 30 seconds for a darn single medal. Sure it offers cosmetics and etc, but I especially hate how bad the casual matches are due to low exp and btd. It seriously needs improvements, in terms of gameplay, very good.
