possible lee sin nerf

so lee sin is a champion with a small finite energy pool that is recovered quickly passively and with AA. all first casts of his abilitys cost 50 energy and all second casts cost 30. which is fair considering he only has 200 . . .fair . . . except for his ult. arguably the most powerful part of his kit DOESNT have a energy cost. i mean i can understand why. since the full use of his other abilities costs more energy then he has, but thats why his passive exists.

i propose adding a energy requirement to his ult. i wouldsay 50 would be fine, this will add windows of power to lee sin that he simply doesnt have otherwise. and force him to utilize his abilities with more care rather then just throwing them around like they are nothing. it also makes it so that his full damage combo cant be pulled off with a ward hop engage meaning he cant just point blank Q you in the face while you are E slowed kick you and kill you. it forces him to AA you a few times before giving you and your team the reaction time needed to be able to deal with lee sin

possible nerf, people might think this will gut him late game i disagree, i think this will force lee sins into the late game role they SHOULD be playing which is bodygaurd/pickmaker. not solo 100-0 adc with zero counterplay man
