I am waiting more than 1 year and they still didn't support controller for android. Picking artefact to sacrefice is harder because I need to touch small "-" button to undo it, this makes me backpain and finger cramp. Oh Don't forget Mihoyo scam at domain crimson witch of flames and thunder furry, those never give me cr% & cr dmg forever. Everything is gacha'ed even at core mechanics because Mihoyo wants player to keep playing, and it's mean you're cursed.
