I hate Fiora's Vitals

It is so incredibly annoying to constantly have to back away from the minion wave, far enough to lose the vital. Specially when you return only to get it at an even more convenient spot for Fiora. It feels as if that should have some sort of cooldown to it, specially when you are playing a mid-late game melee champion and you can't afford the consistent true damage from the vitals.

This isn't a Fiora is OP rant, I am just venting my frustration with what seems to be a silly game of lose the vital spot. Constantly juggling which spot you should leave the vital spot on to make it more difficult for Fiora, but that doesn't even matter because every few seconds it resets anyway and it starts all over again. So annoying :/
