Fioras Q needs a second dash
Make it so the first part of the Q is the skill shot but the second part is targetable. This way she has an escape that isn't crazy but what the second targetable dash can do is make it so in teamfights or dueling in minions top lane, she can Q to something else if need be to hit her ult target on all sides.
As it stands now, goodluck hitting all 4 sides of her ult in a teamfight. No way in hell you are going to be doing that with one dash
