About resources for rank up

Maybe we need some balancing about material we need for rank up a character... Green 5, Blue 10, Purple 20, Purple+ maybe 30 not 50... And about material for +2 and higher please make it easier to get, we must try hard to get and we know that very hard mode is insanely absurd with so many enemies with their one strong character with full star... Best regards for the dev team from me [Squ4all]
