Been playing this game for years and these are the flaws : relatively low RNG, high cost spell cards, daylight robbing your wallets if you want skins / goodies, meta shifts too quickly, channel language barriers are still there, adding useless features such as ascending amulets / armouries which cost tons of exp and gold just to get to level 20 out of 25 PER piece, server always unstable or crashes frequently whenever I entered in repeat modes in arena.
