@Riot and Community: Who do you feel is "inflexible to balance"?
What I mean by that is that the Champion in question is hard to give any buffs or nerfs without either becoming super-OP or super-weak. For instance, give the current Warwick any sorts of buffs, and he becomes oppressive. Or you could look at Irelia, who simply can't receive buffs because her kit is too diverse.
So who do you think fills in this category?
I personally feel
fit the bill.
, but they're getting work done soon for that exact reason.
is fkn broken now that riot buffed him
have too little in their kits, IMO, to be balanceable without strapping on a gimmick like they did with Garen. They're just TOO simple for the direction League is heading in
