Guess who the only champion with 5 different things in one basic ability is then read this.

W: stun, slow, attack speed slow, damage, and a dodge
And remember, this is just a basic ability.

W: stun, slow, attack speed slow, damage, and a dodge
And remember, this is just a basic ability.

W: Speed boost, damage, knock up(triggered when you try to dash inside it), extra resists, more extra resists E: Dash, knockback, stun, damage,

It can only stun or slow Damage is not only trash but AP You also have to stand still when doing this Also it's a very long cooldown
Just because it can do 5 things, doesn't mean it's great at all of them, please. You're trashing on all other champions and praising Fiora like she's on another level than all other champions, but there are obvious downsides. I can make anything sound OP if I don't explain why it could be negative.
Oh my god there is a champion who every fourth basic attack crits and deals missing health damage too omfg
Oh wait, you also have trash attack speed and have to wait after the fourth bullet
Oh my god there is a champion who can toggle between extreme damage and extreme life steal wtf
Oh wait, this means that he has to push the wave for life steal which makes it harder to win laning phase when the minions are pushed and extra damage costs your life
Oh my god there is a champion who can teleport every 3 seconds and deals damage too riot please
Oh wait, it costs more and more mana every time
Oh my god there is a champion who can dodge abilities while slowing and if you dodge an ability it stuns and also deals damage
Oh wait, you have to stand still when doing this, it deals AP damage, and it's a very long cooldown, nevertheless the dodge is less than a second long
Plus, you forgot Fizz-
E makes you invulnerable, a gap closer, an escape, deals large AP damage, and slows.
It seems like you're just salty after losing a match against a Fiora
I find it curious that an ability that counters with damage and a stun/slow also deflects ALL attacks/abilites during this time and not just one. This is the main problem. Fiora is a duelist so excelling at 1v1 makes sense. Being able to parry/counter everything that happens in a teamfight for riposite duration is ridiculous and does not make sense.
the dodge is telegraphed and then followed up by a counter - just like jax's
the attack speed and movement speed slow are pointless if you counter an immobilization ability because it stuns instead of slows.
the stun and slow are interchangeable - just like 
besides all of that it has ability power scaling on a 90% physical damage dealer.
