Money grubbing liars. You used to be able to compete without paying, but those days are gone. Spent a year's worth of earned coins for 7 (seven) summons... yes, they are that expensive. All garbage. Got the only 6 useless heroes available for the summon and thought the next one must be at least usable, right? NOPE. They just gave me a repeat of one of the previous 6. Everyone I've talked to in game says the same thing.
