Fiora's ult is a slow, awkwardly paced Janna ult.

no

Its 4 passive procs (percent maxhp true damage [potentially over 100% maxhp]), a permanent movespeed boost while near the target, and a potential heal whose numbers put Janna's ult to shame

Also dont you fucking dare try to say that her old ult was anything but an abomination that should have never been in the game. It didn't "fit her character," it took the idea of a noble duelist and fucked it in the ass until it bent over, sobbing, saying "fine, fine, I'll give up on elegance and counterplay, just give me a stupid DOTA-clone ult!"

Without the knockback.

The heal is a viktory celebration. Although I expect it's numbers to take a hit.
