Recent in game events (echo event) have made this game exhausting. I don't want to be on my phone for hours just grinding for an event that I won't be able to finish without spending money. You've ruined a good strategic game. It's now a collecting game of marvel characters and the only way to be the best at collecting them is spend money to obtain them. Each character or team released is more powerful than the one before it. It's ridiculous. Don't play this game if you aren't a whale or kraken.
