Why Not Make Fleet Footwork Only Work Against Champions For Ranged Champions?
I feel like it's a win/win.
For opponents, it means the person using FF can't heal off waves. For people using FF, it means you can't waste it with off creeps (the heal is much lower).
Then, I feel like tuning the heal of FF up or down (depending on if it becomes too weak or too good) would be easy after that change.
Goal: I feel like it would be much healthier to make the heal/MS strictly when in combat (AA trades/skirmishes/teamfights), not sustain off waves.
