Every 8 hours we can request cells, but donating cells is only once and maybe twice every 24 hours possible.
I think it would ben great if we can donate also every 8 hours.
Also it would be nice if the ammount of cells donated can be dubble all the time. So 10 legends, 20 epics ect.
Also it would be more honest if low level players can request the same amount of cells as high level players.
