There needs to be a turn limit. People taking 20-30 minutes per turn is ridiculous. Five minute turn limit max. Gem prices are too high. Card crafting costs are too high and breakdown payout too low. Inability to break down some cards even when you have more than the deck limit. Ultra rare cards are in the best decks and if you happen to have poor luck, best just start a new account if you're FTP because you won't have a way to get many gems after a certain point.
