Fiora heals a bit too well
Seriously, she has a lot of easy even before
with her passive 30-115. Her ult heal is broken since it scales with 60% bonus AD on top of 140 base every second for 2-5 seconds in a massive AOE.
I get that she is a duelist, and should be able to hold her own in any 1v1 at some point in the game. But that sustain is too generous for a champion who also is a massive dealer of true damage with almost most attacks.
