I do know some people quit over the gacha changes. Making it harder to aquire slayercards AND resetting the eventbox without the least bit of compensation probably pissed them off quite a bit. I know I'm thinking about leaving Pero myself, and focussing only on FKG instead of playing both. Both because of the gacha reset, and because I won't have to spend ten minutes of every hour for 8+ hours a day on FKG to play.
