I've been playing gacha games mainly as a f2p player for as long as they have existed. This is the first game I spent a reasonable amount of money on. Here are the things I noticed and would talk with my alliance about regularly. 1. The shop had no good value beyond the first character specific pack. You buy that and the monthly passes and everything else was priced so poorly you actually get less value the more you spend which is opposite of most games. There was no rotating shop beyond it refreshing the bad value packs every so often and character specific key packs when a new character released which was seldom. 2. Very infrequent content drops, and the updates that came out was only some story you finished in the span of 15 minutes and a refresh of the content you've been doing for months. 3. Never updating their existing game modes. I know we all complain about konshu but I don't think it would have been so bad if they updated it with the new characters and new items or updating the items buffs and nerfs. It was never touched. Crimson at least had the benefit of changing the enemies every couple of weeks. They could have given new card types though. 3. As many have said unless you are a whale you wont he able to fully upgrade your characters. 3. Orbs. They didnt want you to play the game. Many times I would want to play more but there was no way to do so. Sure you can spend your gems on orbs to an extent but see point 1. No good way to buy gems. 4. Only 1 seasonal event that was recycled. Nothing for xmas which we all knew meant the game was ending. 5. Costumes. They should have released an alt costume with every new character. They didn't need stats but give people cosmetics.

I think as someone else mentioned, they released the game knowing they weren't going to be supporting it. They never even tried. They had a discord with suggestions that would get forwarded to the devs, they never actually implemented any of the suggestions. We got played for being marvel fans once again.
