to be accurate its more of actively knowing how to reset instead trying to play safe and then get owned when i go to chance things. I also dropped less stuff and cleaned up a good portion of inputs on my end
I'm going to keep this short, because going over every little mistake is pretty tedious, annoying, and a waste.
1) You started the round off with something new everytime. That's a good/bad thing. Good in the sense that TJ will NEVER know what you're doing. Bad in the sense that I don't think you had a clue what you were doing half the time and you were just trying things (which is perfectly fine, that's what sets are for). Just saying, if you're looking for a set flowchart plan or if you're trying to random someone like TJ out, It's not gonna work.
2) Why did you try to punish TJ so much with BFF? You probably spent half the meter you accumulated in the set trying to punish TJ from almost full screen with BFF. I want to say it worked 4/20 times...maybe. I understand you're trying to poke holes in his defense, but whiffing BFF and burning your meter isn't the way to do it. Your losses will certainly outweight your wins with that strategy.
3) Your resets were predictable with Filia. TJ caught onto your air-grab resets by the 12th game. On a positive note, I do appreciate your effort in Cerebella and making TJ's Cerebella look Day 1'ish by hitting him with the typical run-stop shenanigans. tl;dr If you don't know alot of resets, space them out or just complete combos and start back at neutral (as bad as that sounds, confirmed damage is alot better than supposed damage against a Peacock, which TJ will DHC out and will heal ALL that red health back).
4) You Raw tag...a lot. Like A LOT. Like, More than TJ ALOT. And it's predictable. Dash up, Raw Tag. Stop it. Never do it again. If you can't get the character out safely, Don't raw tag, you lost Cerebella 4 times b/c you wanted to save your Fukua. That's literally suicide by martyr.
5) There were roughly 5 situations where you could have killed TJ's peacock while just finishing your combo and DHC'ing. Like Sage told you, TJ relies on both Bella and Peacock fairly equally (but it's obvious his Peacock is the anchor). If you have the opportunity to kill one, take it. Peacock builds meter really well. If you have to give him 1 1/2 meters to get the kill....get the kill. Don't put the situation in a 50/50 where he might escape.
There were many other things, but they were small, like execution errors, bad movement, etc etc. I'll be a parrot and repeat what Mike said. Do everything with a purpose. Even if you're trying something new, have a plan behind it. Otherwise when it works, you don't have a fucking clue what to do. And if it doesn't, you don't have anything to fall back on.
Edit 1:If you're feeling I'm being too mean, or if I'm not helping let me know and I'll stop posting on your thread.
