Still looking for another champion to run in my champ pool. So far 
is making that list (thanks to Proguides Geniuses making that recommendation based on my needs). I am looking at 
and have played her in the past. I like the way her kit flows and most of it's interactions. Is this champion very sound right now, or should I stay away?
She can be very good, a hard carry in fact if you are good, but she is very reliant on how good YOU are with her.
My advice is to drop her because all anyone needs to fuck you over is to buy 
+
i played fiora in the past, she scale very hard late but she's kinda weak early, moreover she is difficult to play effectively works good against tanks (i loved playing her against sion)
she can be very rewarding to play tho
She's great...if you're great.
She's kinda like Riven, but with more skill (in W timing, mostly) and less knowledge (because you don't need to know about animation cancels). Great into most tanks. Varies widely against everyone else. Can definitely carry 3v6. Just be wary of people who can rush Bramble without hurting themselves.
she is all about dem 1v1 me bro on dust gameplay, if you get ganked up on by 3 or god forbid more people and they bait your parry you are dead simply put. But 1v1 she can beat anything IF YOU are GOOD with her.
I don't recommend Fiora
can mess her up easily
try
