Random is still broken/rigged for shield generation on alliance wars and tournaments. Upd: several versions later, the shield generation is still rigged on alliance wars and tournaments. Will it ever be random as it should? Also the game is extremely greedy - you can make 3x10 (approximately 100$) summons to get only one 4* hero, none 5*, and all other 3*, which are of no use most of the time.
