Fiora's ultimate
Please revert it please. Both gameplay and theme wise this ult is terrible. Blade waltz was one the single coolest looking abilities in the game, the new one is bland and boring. Riot says her new ult Is ok thematically because she's a duelist and duelists challenge people. This is bad because her kit was made so focused on this one tiny aspect that the kit says nothing about her as a character. Blade waltz defined Fiora far more and far better than her current super lame ult. it doesn't even have an animations. It's a generic kit that could be slapped on any duelist type character and be okay. This is bothersome because why does her kit say nothing about her other than "duelist" when there are several assassin characters who's kits define them as more than just "assassin" and several ninjas who are more than just stereotypical ninjas. Honestly riot fucked this up and need to fix it.
Tl;dr riot made Fiora's ult very generic and bad and need to fix it.
's Alpha Strike glorified, and was only good at finishing 1 person off. It was utterly bad in team fights, and the CD was much higher too. Grand Challenge gives her more than just that, an AOE heal that is lovely in team fights, and more sticking power, and she doesn't have to wait all day for it either.
