Fiora W
I have not always been a fan of Fiora but she's pretty easy to deal with tbh. However, her w is completely unnecessary. She does not have to aim it, and when she uses it she blocks ALL damage, and ALL CC while in some cases returning it to the champ who used a cc ability or similar. In addition it slows attack speed by 50%. I think this ability is just too much for what it is. The fact that you don't really have to aim it to negate cc and damage, but when you do hit someone it slows attack speed and movement speed is just beyond me. Some might argue about Malphite and other champs with a 50% slow, but in most cases they are pretty immobile while Fiora can just dance around you like you're some strip pole. I always wondered why riot never really fixed her w, its too much power with very little skill.
has her W
has his E
her passive and all these imo are better than Fiora's W dont get me wrong its a really good ability but is way harder to use correctly than the others her W is very short instant but short in the duration you need to be really quick on the dime to block most CC you more of the time need to predict it if the abilities is slow then its pretty easy but trust me its far from broken or unnecessary
