1.) Bad pity system. You need 30 multis equivalent to 15k gems just to pity and the pity is not transferrable to the next banner. The pity count is converted to skip tickets, which you can get easily through story modes. 2.)Little to no endgame obtainable gems after clearing story mode. You can get a max of about 7-8k free gems from clearing the modes and that's it. 3.) Horrible UR rates. Some spend hundreds of dollars where they get absolutely nothing. Fix these issues before the game dies.
