Kled W

I don't know if this qualifies as a bug but it is something that is annoying when I play kled. When Kled auto attacks it activates his w but when I go to attack a minion and cancel the auto attack because I decide to save it because my jungler is coming to gank it still activates the w even though I never hit the minion. I don't know if this was intended but it would be really cool if your w only activates if you do dmg/hit your target.
