Repetitive covers

I think it's really bothersome that no matter how much you play, you only seem to get the same 1* and 2* tokens when you use recruitment tokens or event tokens. Even with the deadpool tokens I get the same garbage covers that I don't want or need to be able to level up characters I actually care about. The amount of time that we put in to the game should be recognized and rewarded because with out us there wouldn't be a game. Anyways just a suggestion because it's very frustrating to finish a really hard challenge and get a venom cover it a hawkeye cover that's 1*
