In my opinion rukia rei boost on going bankai should be buffed. It isnt sufficient hakurens rei drain is 2k with like a 10 sec and shirafune 2k rei drain and a 10 sec c/d and ice freeze has a 1k c/d. It would be better to make hakuren 1k rei drain and ice freeze 2k rei drain shirafune is good as is. I'm just trying make game more balanced, because ice freeze is more op than hakuren so it should be a higher rei drain and hakuren should be lowered.
