I.....beg your pardon?
Honestly, I believe that the lower tiered characters should be buffed, but the upper tiers barely altered. Extend was sort of this way (with the exception of Makoto and perhaps Tsubaki) where it was hard to place who was lower on the totem pole, though some would say Tager and Rachel as well.
This thread may as well be the Tsubaki fan club HQ. At least she's getting some shine.
And I vote no to overpowering Izayoi. I enjoy playing a rare character.
Characters with meterless reversals and stand overheads:
Ragna, Tsubaki, Bullet, Hakumen, Litchi, Tager, Makoto, Kagura, Mu, Noel (heh), Azrael
Are who come to mind off top
Every character has unique properties. Noel can whiff her drive and keep going. Ragna can steal health. Terumi can steal meter. Valk has mix up for days, etc. And as for damage, I wonder where your complaints were when Haku could get 10k in Extend for 8 stars.
