Riot, you're taking a few steps in the right direction for Fiora, but there's still work to be done.
Biggest thing that HAS to happen is Fioras hair style MUST be the same as current Fioras. New hair doesn't look good, period. Royal guard needs an adjustment to her chin, and that shirt you added should leave. It's not fair for those who bought Royal Guard that you should change it in the way you did. This isn't really an art thing, but an AoE heal for her ult? Are you joking? That's just ignoring the thematics of the champion. Her signature ability was arguably Blade Waltz, and I would take that over this "thing" any day.
