irelia has been busted ever since the rework. even past every nerf they gave her she was still busted. then they buffed her for some reason.
point is that they have no clue on how to balance their own game. to me, the most busted component of her kit is her passive.
she presses Q on four fucking minions and now has tons of AS, conq proc, damage, etc. and if she hits her stupid hitbox stun then thats two q's on you. three if she ults. all in that period you really cant do anything but die.
btw on the balance thing. i just did a bit of testing on the tower shield plating to see how it works. the tower plates literally does nothing but grant gold for breaking the shield. it doesnt protect the tower in any way nor you. when you break all the shields the tower dies, not reveal the true health of the tower. if you destroy like half the shield, once the sheilds decay the tower gets no health back for segements or anything. the shields do absolutely nothing.
