For anyone wondering, Flame-Forged R5 vs Master Key R5 for Aino, short answer if you have FF R5 use it, else get MK: essentially FF has 45EM more and Energy management is similar (slightly better for FF even). Ngl MK does look better on her, but not wasting a perfectly viable event weapon because of that.
