4star Rank Down Tickets in Store
Here is my suggestion. Add rank down tickets for 4star champions to the store, for reasonable price of about 800-1000 units per ticket, to let players who progressed above 4star champions stage - to recycle catalysts that they have earned, from champions that they are not using anymore. In my opinion, game has already reached the state, where it couldn't be abused. I also feel like it is very much needed option in game, where 5star and 6star champions use the same rare rank-up materials, as 4stars. Express your argumented opinions on that idea!
