I've summoned 200 heroes. I have 52, 52 heroes... it's 1980 gems to summon 10 times, which means around 75% of the time it's duplicates! I've literally spent money to get duplicate 2 & 3 star heroes. Also, out of those 200 summons, I've got 3 5 star.... 3 out of 200..... The graphics are great, the game can be fun, but I'm not so sure it's even worth downloading for a cash grab game... I'm just disappointed
