Fiora's Rework: My Two Cents (New Placement!)
So, Fiora's officially getting a rework. Here's a concept I came up with.
My reasoning on this rework: Fiora currently fills a niche which is only shared by Riven, that of a high-powered, squishy-ish, feast-or-famine top-lane carry. I thought about this and decided that Fiora's current power comes from two things- her ability to do immense damage in team fights via Blade Waltz, and her single-target dueling capability. I decided that, since Riven already provides the teamfight threat from this niche, to focus Fiora on dueling/assassinating single enemy champions. Accordingly, I tried to tune up her power against single opponents (or possibly pairs of opponents) while reducing her ability to shred an entire team in a teamfight with the press of an R key.
Passive: Duelist Fiora's autoattacks and damaging abilities mark enemy champions with Duelist for three seconds (if a target is damaged multiple times, this refreshes the decay timer). While within 600 units of a marked target, Fiora's movement speed is increased by 5%.
Q: Lunge Cooldown- 15/14/13/12/10 seconds Fiora lunges to an enemy unit within 600 units, dealing 80/100/120/160/200 + 40% AD physical damage. If the target was marked with Duelist, Lunge can be cast again within 3 seconds and slows the initial target by 30% for 1/1.25/1.5/1.75/2 seconds.
W: Parry and Riposte Cooldown- 9/8/7/6/5 seconds (begins after the active times out) Passive: Fiora takes 2/3.5/5/6.5/8% reduced damage from targets marked with Duelist. This passive is lost while the ability is on cooldown. Active: Fiora blocks the next autoattack from a source marked with Duelist within the next 2 seconds. Fiora's next autoattack against a target marked with Duelist within the next 3 seconds after the blocked autoattack deals 100/120/140/160/180 + 50/60/70/80/90% of the damage blocked (before resistances) as bonus damage.
E: Press the Advantage Cooldown- 12/11/10/9/7 seconds (begins after the active times out) Passive: Fiora deals 2/3.5/5/6.5/8% bonus damage to targets marked with Duelist. This passive is lost while the ability is on cooldown Active: Fiora gains Advantage, a self-targeted buff, for 5 seconds. Autoattacks against a target marked with Duelist during this time interrupt channeled abilities, slow the target by 20/25/30/35/40% for 1 second (autoattacks after the slow is applied refresh this timer), and grant Fiora 5/6/7/8/9% attack speed, which can stack up to five times.
R: Coup de Grace Cooldown- 50/45/40 seconds Active: Fiora's autoattacks and damaging abilities deal all their damage in true damage against targets marked with Duelist for 5 seconds.
Tell me what you think!
TL;DR: GO BACK AND READ IT, I PUT GOOD WORK INTO THIS!
basically all need to ult to get their second.
needs to at least hit 6 before he gets his.
Having both on QWE allows close to 100% up-time for Fiora, which is nifty because melee AA's are more of a spur-of-the moment thing than something you really plan to happen.
Also in environments where you can legitimately run a melee ADC and be better than a ranged ADC (Treelines and Dominion), low cooldowns and 100% up-time on AA steroids are much better suited for such environments and play-patterns.
Also:

are tanky-derps with how the meta uses them in competitive play despite appearing as lighter champions.
