Fiora
I'm not sure about anybody else's opinion, but I feel that Fiora needs some kind of a gameplay update. Maybe it's just me, maybe I just don't know how to deal with her. But what can you do when she ults in and does unthinkable damage to squishies? Her ult makes her untargetable, and unlike other champions, say Katarina, or Master Yi, who just do a quick shunpo/ult or ult/alpha strike and just need a quick silence or cc, Fiora's ult cannot be disrupted or countered. I'd like to see something done that prevents her from automatically wrecking squishies just because her ult makes her untargetable and does the damage for her.
