This sounds like a great thread, I think elsa is just too weak of a character right now and needs some serious buffs.
I think 4c needs to be jump cancellable, its silly that I need to pay meter to get anything off it.
I think communio shouldn't even have a cooldown like tempered said, then I can use it like akuma air fireballs.
I think 6b should be overhead since elsa has no mixup.
I think that bottle should have faster startup, its hard enough to get people to respect my pressure already.
I think that communio should have more hitstun, I simply don't have enough time to do what I want off it.
I think her critical heart should have a use.
