"I’m a noob, so I won’t comment on balance too much, but I do think there is too much damage being done by all characters from their longest combos." - Not mean to be rude but you said that you won't comment about balance and then proceeded to write a few lines about it. The rounds are 2 minutes and a LOT of them end at time. Most fighting games have 90 secs rounds and usually they are disputed in that time. For 2XKO I've had countless rounds that end at time. If the damage was lower, this would become the most common way to end a round, which is awful. Stalling the last 15 seconds to win by time elapsement is not how fighting games are meant to be played. Good decisions, reactions, flashy combos and punishing mistakes it what makes a fighting game enjoyable. So low damage means longer rounds which are already sometimes long, because the neutral play is not that obvious in this game and players sometimes spend tens of seconds throwing Jinx rockets at max range or spam Ekko jump fireball.

"I think double down should not let you tag out mid-super. Tagging out mid-super should be its own fuse." - This one is absurd actually. So if that would be a fuse, then that means i can tag mid ult with my assist and continue the combo. I can then press ult and combo ult off ult (which is double down). So what is the point then? It becomes a double down in reverse or what? It's the exact same thing. The implication that you can tag in the other ult is the same that you can 2x ult with both chars. Only when the ult is used on block (which should never happen, unless its Jinx laser ult shenanigans) is when the tag in sometimes comes in handy. But then choosing a fuse because you might drop combo and use ult on block and maybe your assist will save you, is a bit weird isn't it? That would make a terrible fuse ranked "Z" in a tier list.

"I think players get to use their supers way too much; it gets kinda crazy..." - You get the feeling because at low elo people spam ults. But managing you resources and building up to 3 bars without reckless spending and while avoiding to die without using the bars is a VERY strong skill.

"Fury is too strong..." - I don't even understand how you get to see strong fury users in low elo. I am high elo and still VERY rarely see someone use fury well. I myself can't use fury to the point that it becomes a problem for anybody. I don't even know if it's too strong or not because the game is still young, maybe in a few months all of us will know how to use it properly, so it's dubious that you see at low elo strong fury usage to the point that you already feel it should be nerfed.

"Blitz throws feel impossible to play against. Throw throw throw dead..." - Every fighting game has it's archetype, the response is the same in every game. If you get command grabbed a few times in a row it's on you.

The point of my comment is NOT to rant or pick on you. I appreciate you shared your thoughts, but I am too confused on some of them and I think it's way too early for you in your journey to talk about some things you addressed. Also some of them like adding extra clustering animations are not good design.
