Ideas on how to 'fix' Fiora

So, lots of people hate Fiora, and I can understand why (no CC, no burst, no escape, item dependent, squishy, other champions do the same thing but much better); but, I still play her a lot, I think her playstype's really FUN, and I think fixing her wouldn't be that hard. So, my ideas: 1.) increase the CD on riposte, but make the CD decrease every time fiora gets hit by an enemy auto attack Reason: currently this ability is really strong for swinging early level fights since each auto attack is significant, but, late game when you're fighting an ADC or bruiser (jax, olaf, irelia) with 2.0 AS it becomes massively insignificant especially considering that, compared to other shields/blocks, it can't defend against any spell damage or turret hits. This change would make fiora's dueling ability during the entire game pretty consistent and still late game relevant, even against a jax. 2.) I feel like lunge (her Q), should get some CD refund on kill/assist to help reinforce her role as a mobile melee adc in teamfights. OR. Make the CD reduce with her auto attacks and just incease the base CD. However, to compensate for this the movespeed bonus on burst of speed should probably also be nerfed into the ground, not removed, but massively nerfed.
Reason: as of now fiora's great at leaping into a fight, but once she's in she's not terribly mobile even with burst of speed and can be fairly easily kited by adc's and mages (or she gets blown up and dies, because she's fiora). Alternatively, instead of CD refund, make it mark her tagets somehow (maybe armor reduction, percent damage incease, vision and movespeed toward the marked target, idk, I just feel like it needs something and this would add to her 'duelist' title, or, I could be wrong about this change and the ability's fine as is)
3.) instead of having riposte's passive give her flat AD, make activation of burst of speed cause her AA's during the duration to do bonus damage. Reason: while getting roughly 1000 gold worth of free AD is nice, this change would actually give fiora some burst damage, which she badly needs. 4.) when Ripost parries a champion's AA, make it root the champion in place briefly (0.5s-ish). It doesn't need to be much, but giving her some CC linked to her dueling would go a long way toward making her viable without making her op. 5.) Her Ult... while it was somewhat fixed in a recent patch, currently it's still basically just Alpha Strike with a massive CD (ok, not exactly, AS doesn't apply on hit effects like hydra, but Blade Waltz can't crit and doesn't get CD refund and isn't a spammable way of dodging every ability on the planet, and yes, I hate Yi the way most people hate fiora). What would I change? Not much actually. Maybe nerf the flat damage but add percent missing health damage (not mitigated by same champ hits) to make it more of an execute than a AOE entire team nuke (with Hydra). Maybe also have the CD decrease with AA's against enemy champion, but that would probably be op. Reason: this would change her ult to make it more viable to execute an enemy in a duel (considering that currently, in a 1v1 fighr, particularly at early ranks, her ult is more or less useless unless you're tower-diving or being tower-dove)or a way to come back and win a close fight rather than a way of initating a teamfight or cleaning up an entire enemy team with the AOE from hydra. Don't get me wrong, I love nuking entire teams with 400+ AD and a hydra, but I think this would put the ability more in line with fiora's "Grand Duelist" title and make her kit less schizophrenic between massive teamfight aoe and 1v1 dueling.

Summary: these changes would help fiora's dueling potential while reducing her face-rolly teamfight dominance when she gets ahead while also fixing SOME of her problems (she'd get a bit of CC and burst damage and the changes to riposte would make her pseudo tankier). These changes don't give her an escape or change the fact that she's massively item dependent and a very 'all in' champion thus maintaining her identity while making her viable rather than the only champion people hate more than teemo.

TL;DR: Dear Riot, Fiora needs a rework and it really wouldn't be that difficult.
