About the Fiora rework... Just some feedback.

A couple compliments and a couple complaints. I'll start with the positives.

1. Her passive and Q interaction is interesting to play with and creates a different lane environment, so that's kind of nice. It actually feels really good to execute properly.
2. Her W + E feels REALLY good. I can see it securing a lot of kills and winning plenty of pre-6 duels.

But...

1. Her AA animation feels absolutely awful. It takes too long to deploy, and it's really easy to accidentally cancel it before the damage goes out.
2. Her ult feels completely useless. Against foes with strong ults, you can't save it for when you or they are low, and as soon as you activate it, they just run. The short duration ensures that nobody will get hit on all 4 sides. At best, you pop this on a low health target in a teamfight that you know you can hit, and it's a super conditional Janna ult w/o the knockback. In lane phase, you almost resign to losing every duel from 6 until the team fight phase begins. It feels TERRIBLE.

Her ult would be usable if while active your Q had no mana cost or cooldown, so you could use it kind of like her old ult, except with a ton more counterplay (like slowing/stunning her), and only really good against the marked target. Just an idea.

Ultimately, I just don't feel that a champion who struggles to win 1v1 is going to do all that much in the 5v5 scenario, especially with no aoe and very limited CC. The question to ask is: Why pick Fiora when other fighters/assassins contribute so much more?

EDIT: Thinking on it some more, she has excessively long cooldowns. I'm not sure this is necessary for someone who depends on mana. Maybe remove the mana bar entirely, or reduce the cooldowns significantly. The Q is fine, though.
