The idea of crit on Lunge is that when she procs it while using Lunge, the total damage is increased by 50%. Also, I also hope for it not to be used as a burst, that's why I change the cooldown mechanic so it benefits players who don't use it to burst.

And no, she doesn't most out-sustain champions. Even a Irelia can out-sustain with just her passive W compared to Fiora. She can only out damage (which doesn't change since that's all she really has) and her main form of sustaining coming from acquiring life-steal (which means it doesn't come from her kit). This change barely improves her sustain. The only way is to stack health like crazy to even see a marginal difference which by that time, it will have easily past the lanning phase.

And look at what your saying, you don't want her to out-damage champion or out-sustain, and if you don't touch that, what else is there to improve her without out-right reworking her kit. The only other options how just lower cooldowns and mana cost.
