Been playing this game for awhile now and I realize it's just a scam, don't spend money on gems because you won't get any good heros, it's extremely hard to progress through the game, I just spent $10 and have spent more money before, can't even get a 4 star hero, it's absolutely ridiculous, I would spend money if it was worth it, but unfortunately it isn't, need to fix this if you want anymore of my money.
