Patch was crazy, gonna take a while to figure out the game again. Should be interesting. I'm a little concerned that Johnny's only armor now is a high, which means you can't armor a poke anymore. It may not end up being too bad, but it's something to watch out for. As for the FistBump change, one thing to note is that you cannot cancel it into block. So if you don't cancel it ExFistBump has the same recovery as the normal version. So make sure you're jailing or they have no meter. This means that on block 113xxExFistbump is pretty easily interruptible. (Kinda wish you could also cancel ExFistBump into Throw... but that would likely be way to much.)
I kind of wish the cancellable FistBump wasn't a meterburn but just a normal Ex type move, because it's pretty annoying to do normal 4xxBF1 then block now(since that is -6/7). In order to do that you have to do 4xxBF1+Block because this prevents you from spending the meter while blocking on the earliest frame. That should just be muscle memory though, so it may not end up being a problem. But right now it seems really easy to accidentally spend meter when you just want to block after FistBump.
ExFistBump grounded combos into speed bag seem to have some pretty jank rules to them. Like after doing 8 hits of speed bag into ExFistBump you can only get 3 more hits of speed bag after it. After doing 113 into ExFistBump you can get 7 hits of speed bag. After doing 4 hits of speed bag into ExFistBump you can get 5 hits of speed bag. Seems odd but may not matter since doing speed bag after the cancel generally won't be your best damage option.
F3xxExFistbumpxxBLANK will only jail with an 8 frame or faster normal, meaning that you can only jail from F3 with D1 or D3. So there isn't a huge risk to try and armor though a F3xxExFistBump. Standing 4 doesn't seem to combo with ExFistBump, but does jail into 13 frame stuff. Standing 4 is the only normal that jails into anything on block after ExFistBump. The F3 cancel is likely around +6.
You can juggle off of F24 & 333 into ExFistBump into D3 in the corner. Not sure how useful yet.
Midscreed off of speed bag you can do b12-12-12-12xxExFistBumpxxF4, f24, b12, f3xxBD3 for 32%
you can swap out the juggled b12 for just 12 which is easier and lose 1%, so 31%
Having a 1 bar 47% corner combo off of F3 seems pretty good... which after you can use another bar and guarantee 333xxExDF2 for 12.05% chip and be at +4. Turns it into a 2 bar 59% combo that leaves them standing at +4.
Btw the one I was using was F3xxExFistBumpxxF24, b12, b121, b121, b12-12-12-12-12xxBD3
Also getting a 1 bar 38% combo off of 113 in the corner seems solid. The old way using ExNutpunch was 36% but had armor to cover the gap if it was blocked. But if the Nutpunch was blocked you were punishable. But now you can't really cover the gap, but if the post-113 actions are blocked you should be safe. So it isn't a strict buff in this scenario, it just has different risks.
In the corner, if you connect with speed bag the best combo now would be something like b12-12-12-12xxExFistBumpxxF4, b12, b12, b12, b12, b12-12-12-12-12xxBD3 for 41%.
After all of these you can use another bar and guarantee 333xxExDF2 for 12.05% chip and be at +4.
The best part of these changes for combos is that when you finish the combo you already have FistBump active for the pressure/throw. It's a pretty big deal.
Also pretty important: After a nutpunch without FistBump active, for 1 meter you can get 4xxExFistbumpxxF34 for 6.2% chip and jails. Doing 4xxExFistbumpxxF244 is 7.4% chip but has a 1 or 2 frame gap. Meterless, the same as pre-patch, you can just do 4xxFistBump. Which is -6/7 depending on hitboxes(breathing and the like). But note above about blocking after it.
Overall the pressure changes don't seem to crazy, they all have gaps into strings except s4, so nothing broken really.
The big changes here are that FistBump will now be active for a much larger percentage of a match without having to sacrifice a ton of damage and that you end a combo with FistBump already active. This may be enough to make him pretty good. But we will have to see how the rest of the cast plays out first.
As always, sorry for wall of text.
