There isn't much to do, I pretty much lost interest once 2x drop are gone plus refreshing in arena just to find someone you can beat isn't really fun since it takes a lot of time. I'm also not looking forward to grind gems for 3 months or more just to make sure I get one UR event character, incase I get unlucky with my multis I will need 15,000 gems to exchange an event character. I know the game just came out and its a gacha game patient is key but losing interest this early is not a good sign.
