Before I start, forgive my lack of structured thought.
I think that most of these changes are because of the Guard gauge. Ciel's the only character with a projectile combo, no? And most of these changes seem to be increasing her hit count ((Multi-hit bunker-y thing and Nyanyaya's slashes)) as well. However, my question now is, after she Guard Crashes someone, how much damage will her best BnB deal?
Ciel has 421 and 63214/624 commands open. I have a feeling the aerial keys will be 421, since it's close to 214. ((I'm imagining giving them and Mech Hisui's jetpacks clash frames and listening to the cacophony.)) Anyways, 63214 is still open for the Nanaya, and EX Nanaya could be the bunker... maybe...
Although it's far less effective than 2CC, what about Ciel's
2BB
>j.236A>throw
>j.236B
>j.214A
>j.214BBB
mix-up?
((Guh... too much Brawl. I'm imagining j.623 as something like Ike's side-B))
However, if Ciel really does drop to Neco-tier, I think it'll be interesting to get a large wave of really good players experimenting with the other characters.
