The Good:
j.BC2C pressure is easier to land on smaller characters
6[A]BC j.BC is easier to combo
236B goes full screen now
Can do 22B 6[A] quicker
TK j.214 is easier to perform
The Bad:
OTG 63214C (in Heat) now confuses Neco Arc
j.214C can be jew'd with the newly added Air Circuit Spark
Cannot spam j.A (whiff) rapidly
Traditional 2C 5C j.BC dj.BC combo is harder to pull off at a far range 2C hit confirm. Must use weird delays to connect or use 2C 5C j.CAAB
Far range 2C 5C j.A won't connect anymore
Air dash duration is roughly halved
Obvious Stuff:
Added 421x move set
Added new game mechanic stuff (Guard Meter, Air Dodge, Super Double Jump, etc)
Slight fluctuation of damage when doing the same combo (change in game mechanics/defense/etc?)
Don't know:
Defense
Frame Data
Hit/Collision/Etc Box
No hesitation for an addendum.
