Charge moves require 35f to charge, pushblock animation is 25f, but if you're PBGCing you likely got touched again during pushblock, which will add probably around 10f of hitstop.
What about character matchups? Like, how not-in-one-characters-favor does a matchup have to be for you to want to change something? And what ratio of the cast does a character have to have good matchups against before they're considered for a nerf?
Also, cause I'm typing (it's also on the topic of imbalance), any other considerings for other assist differences like updo (meaning would you consider it and are there any being considered)? You probably answered this already at some point, but I'm curious.
Updo isn't different as an assist, it's different as point character because those 3 hits were TOO AWESOME not to keep. Which I suppose amounts to the same thing except that it'd have been 1 hit everywhere rather than 3. Plus it does other things detrimental as a point character, like not being able to get max damage unless they were deep and scaling your combo by 3 hits.
Does Pinion Dash not count? :^P
A matchup would have to be
extremely bad for me to consider changing anything
just for that matchup, because character changes affect other matchups also - like, Tager-vs-V13-in-CT-bad, or Sentinel/Thanos bad. In GGAC, I would've changed Eddie because he's stupid against the majority of the cast rather than for the Potemkin matchup specifically. You need to consider whether it is an inherent character flaw (Tager has no double jump and no forward movement that can be cancelled / Eddie can triple-unblockable everybody / Thanos has no air throw / Sentinel flies backward faster than most characters dash forward) or a matchup-specific problem, for instance if Nu was the only character that Tager's flaws mattered against or if they were universally problematic. Lots of things tend to come down to character flaws, but the way that defensive options work helps a lot with that, I think.
A matchup also has to do with the effort expended to win it with the advantage vs the effort expended to overcome that advantage. Tager/V13 or Tager/Arakune were pretty much an ACTUAL flowchart and it didn't matter what Tager did.
SG doesn't feel like it has anything even close to what would be a 7-3 or 8-2 in another game, to me, at this point.
It does have a community of people that didn't experience those matchups or actually spend years learning how to exploit common tactics from good characters, though, so they don't have a frame of reference. (^.^)
