I think the way fleeted foot is being handled could use improvement

As it is now on the PBE is is an almost exact carbon copy of warlords. And I would exactly call it a problem since grasp made a return revamp in the new runes. When it was first revealed with having AP scalings I thought it was a great idea as a step towards making it more viable for a wider range of champs, maybe even giving it interaction with ludens/runic, but giving it back the crit scaling makes it hypertuned for marksman again and it will have to be balanced around that purely.

I think before bending over and attaching crit, riot should make it a drain proc instead of a heal proc. All of it's potential core/niche users gain a boost in power from it. And if that proves to be not enough or too much, look into adding bonus movespeed into the calculation of the number either the flat bonus or percent bonus. It will still gain improved scaling without being so extremely tied to ADC's.

Honestly i feel that if riot has to resort to adding crit scaling to this rune then the design of it is a pure failure.
