I was gonna post notes on our set after I got a chance to rewatch the games but thanks for posting this, I knew my offer for getting unsolicited advice would pay off :^)
-You gotta work on your hit confirms, a lot of the time you'd hit with something like Filia j.MP or Big Band j.LK then land and go for a throw. Those moves should be hit confirmable on their own. Practice against the dummy set to block randomly.
I'll see if there were times that this happened and I didn't notice but at least from what I remember most of the time (like at least 80%) this happened the reason I didn't get a confirm was cause of bomb assist, filia j.mp/bb j.lk into c.lk with either character combos so it's what I'm used to, so the bomb really messed me up. You sent me the message about confirming into gregor but I was greedy and wanted to try to do it meterlessly so I was trying to do j.hk which got me hit the one time I actually tried it because that move actually has a hurtbox now. But basically at least from what I could tell it's not that I didn't have a confirm, it's that I didn't have a confirm that avoided L bomb. Though there were probably some times that I got the hit on peacock and did nothing with it.
A lot of your mixups were something like IAD j.LP land grab or c.LK IAD j.LK and like, I think that sort of thing is OK to do sometimes but you lean on that stuff too much. When you did a mixup like that usually one of two things would happen: I would get hit by both mixups (so the second mixup didn't add anything) or I'd get hit by the first mixup but not the second (lost your chance at a combo).
The IAD j.lp grab is definitely something I do a lot, I won't deny that, but I wouldn't call it j.lp -> throw 2 mixups. j.lp is obviously not something I can really confirm off of, the reason I do it is because j.lp is like +10 at best and even if they're really close to the ground if I did IAD then they still don't land before me and it ends up being like +4 at worst so it's a really good poke. Grab is USUALLY the thing I do after that because people tend to block but I can do low/overhead as well of course (and tbh I thought that I had adapted and was doing low more because throw wasn't working but guess I didn't, or at least not enough that you noticed). I don't remember doing c.lk into instant overhead at all though...
When you reset, the reset is almost always overhead or throw. Those aren't different mixups as far as breaking guard, they both beat downback and lose to upback (one of them beats neutral back and the other doesn't but w/e who would ever be holding that). They're also risky; a whiff throw is full combo punishable, Filia j.LK j.HP is punishable if they chicken block, L Giant Step is jab punishable etc. If you reset with Filia c.LK and they block that, you can call Big Band assist and go for another mixup. I would recommend going low way more often, like over 50% of the time when you do restand resets. More air grabs/air grab tech baits would be good too (you did air grabs sometimes but you definitely prefer restand throw or restand overhead). More crossups with Filia would also be good.
With regards to "risky", that is actually something I have been working on but wasn't QUITE confident enough to do it vs you yet. Well, it's partially a matter of confidence and partially a matter of breaking the habit of autopiloting j.hk after IAD j.lk (w/ Filia of course). Filia has some overhead strings that combo (j.lp j.lk c.lk if they aren't point blank next to you, j.lk fastfall c.lk if they are) that I've been practicing but again it's a matter of using the things I work on in actual matches and breaking the habits of old strings. I don't really know why I didn't go low much cause I usually go low almost every time lol, I guess i subconciously thought "peanuts plays me he knows I like low I won't go low"? but it wasn't like a conscious choice I made. I did however intentionally not go for as many air resets cause you're playing 2 characters with doublejumps, though IIRC airthrow beats doublejump so I should have probably been going for that yeah.
I thought you played the neutral Big Band vs Peacock well, you were picking the right times to punch, but after the knockdown you didn't get a mixup often enough. Here's kinda how I think of being in a hard knockdown situation as Peacock: if I think you're going to grab I'm going to do instant j.LP to beat it and get a combo, if you do c.LK or Giant Step I'm going to M Gun to beat it and get Argus or Lenny > Argus. If you do a mixup that's not either of those things I don't have an option to beat it that also lets me hit you. To be fair you would do jump in j.LK or Cymbals sometimes but again I think you should have done it more often. Also instant j.MK is a good mixup there.
Yeah I wasn't really quite sure what to do for oki against peacock when I got the brass. I felt like I guessed wrong about what your wakeup would be almost every time. j.lk is something I did try to do but I was trying to do the 1-hit safejump thing and I guess I mistimed it cause what would happen is you would jump, my j.lk was too low to hit jump, and since I was downbacking (thinking that m-bang would be the only thing j.lk wouldn't hit) I'd get instant overheaded. Instant j.mk is something I'll try though.
You need to be able to react to alpha counters, you can Fenrir Drive or Super Sonic Jazz to beat those on reaction. (I'll add that reaction Gregor Samson is not as good an idea as it seems, it loses clean to the alpha counter most of the time. lol gregor sucks)
let's go gregor gregor sucks. But yeah I thought most of the times I got hit by AC I was in the air though, maybe not.
My overall thoughts though:
Vs peacock:
I really hate fighting against peacock, not just because of the reasons everyone hates fighting peacock, but because her hitbox and weight is really weird for my Filia combos, a decent amount of my stuff TECHNICALLY works on peacock but it's so much trickier to do on her that I usually don't try to go for it.
I do need to do the thing you mentioned about contesting going in with held item though I'm still not really sure how, maybe airthrow? I'll watch the tapes to see if I notice something I could have been doing. I also would try to do things that wouldn't work, like countercall with my brass, and it would never work because you'd be throwing stuff to prevent it, but I'd still keep trying it. You did a REALLY good job of protecting your assist, I could usually tag it with Filia lp but every time I did you'd throw bombs/item in a setup that would prevent me from engaging until your assist was back up again. So I do need to find a better way in against peacock at like midrangeish, basically the range where you actually tossing the L bomb will stop an IAD.
Vs bigband:
I noticed late in the set (but at least I noticed eventually) that as soon as you got 2 bars you were VERY eager to throw out ssj to stop my offense since you could just dhc into lenny if it got blocked, so I was basically on a timer for when I could engage bigband. I felt like I could usually get a hit but my mixup wouldn't work or (more often) I'd just drop my OTG and you'd get out for free. As far as defense, I noticed you resetting low so I'd block low but then of course it would be overhead or throw, you did a good job of varying your mixups.
I do think it's interesting that you said my neutral and defense were fine but my offense was weak, when I had kinda thought my offense was the best part of my game and my neutral/defense were lacking. Guess it just means I have a lot to work on lol. But thanks a lot for the advice, I do appreciate it.
