There's also a quick list from the jp mbaa bbs, hopefully someone can translate it:
・都古
何故か暗転カットインの絵変更
C BE5C通常技キャンセル不可
補正値等は多分同じ
H わからん
F 火力が500弱ぐらいは下がった
EXせんしゅうの有利時間が少しだけ減った
20Fぐらいはありそうだが
・HV
EX縦カット硬直増大
とりあえず秋葉敷いてる暇とかない
補正か威力変更?
トレモで対シオン、2A2B5B5C>6C6C>2C5Cエリアルで4200程度
実戦でひっかけから確認で実戦用レシピのエリアル、で4000切った
CVは縦カット硬直普通だった
・琥珀
アッパー補正あるかも
浮きが高いせいでちゃぶ台全く完走しなかったけど、3回目のちゃぶ台で3200ぐらい
バーエーでやりこんでないから変化が分からん
でも、浮き高いせいで4ループ安定キャラと対応キャラ増えそう
・シエル
2A2B3B5C>EXフロウJBJCJBJCサマー投げ で同キャラ5200
黒鍵BAB>EXシンカーJAJBJCサマー投げで4000ちょいぐらい
ちょっと安くなった
・メカ
その場避け
EXワイヤー、Aワイヤー後に相手がメカ側に振り向くようになったので
多分既存レシピじゃ背面ダウンは作れない
Miyako:
For some reason the sprite that pops up during superflash changed
- Crescent:
5[C] not normal cancellable
Proration doesn't seem to have changed
- Half: Dunno
- Full:
BnB damage reduced by about 500.
EX sensyuu (some special move, not sure which) frame advantage reduced
-- still feels like around 20f though.
H Vsion
623C recovery increased -- not enough time to use Akiha summon anymore.
Changes to proration/damage?
In training mode 2ab 5bc 6cc 2c5c aircombo did about 4.2k
C Vsion 623C recovery seems unchanged
Kohaku:
Uppercut (command throw?) proration seems increased.
Since gravity increases less, loops felt weird, but with 3 reps it did about 3.2k
I didn't play her much in ver.A so I'm not sure if it changed,
but the extra floatiness feels like it will allow doing 4 reps on more characters more easily.
Ciel:
2ab 3b 5c ex furou (?) j.bc j.bc airthrow on Ciel herself 5.2k
Black keys (214?) BAB ex sinker (623C?) j.abc airthrow about 4k
Her overall damage is a bit lower.
MH:
Her dodge doesn't move forward anymore.
Her A and ex whips now make the opponent turn towards MH,
so doing knockdowns from behind is probably impossible with the old combos.
Sorry for the choppy translation, to be honest I didn't really know what some things were referring to exactly as I haven't followed MBAA that much, but hopefully it should be obvious to someone familiar with the characters.
