I think the main reason moves like Geneijin, Seiei Enbu and V-ism CC were so good is because they pretty much “guaranteed” damage.
With other supers, if you mess up, then that’s it; it’s gone, and you can’t do anything about it.
With the custom combo moves, you still get a 2nd, 3rd, 4th chance, and you can keep trying or do something about it, and basically guarantee some sort of damage.
With Geneijin, you can keep mixing up until you can land that 1 big hit or custom combo to lead to a big combo, while basically hitting your opponent with overheads all day, because the fear of getting hit by a low attack is MUCH bigger.
With V-ism, in A3, you can abuse it by continuously attacking until your opponent runs out of defense gauge, and then whatever you do after that is free. In some cases, you can even set up an infinite with v-ism.
With Seiei Enbu on Yang, you basically mixup between overheads, low attacks, and command grab so you can land it, and get a slap combo, and then wait for them to get up and do it all again. It’s not as dangerous on paper, but it gets people in the head. I think this is what Juri’s version is going to most resemble.
You’re probably gonna see this move used most effectively when she lands a hit, does a small combo, and then as you get up, starts up another mixup, trying to land another small combo, rinse repeat.
How good this ultra is going to be will depend on her normals and what can cancel into what exactly. Can she cancel a sweep into a jab? Then that would mean all of your moves become safe even on block. Your footsie can benefit from this a lot.
Does she have an overhead normal attack? Then THAT will play a huge part in doing damage. Once you do get in, your main way to deal damage is to probably mixup between the overhead, low attacks, and grabs, until he gets hit by the overhead or a low attack, which you can then followup with a beefy small combo.
Will it have invincible startup? You can use this during footsie or on wakeup to make pokes and moves miss, and then get a free punish, like V-ism CC.
It also makes sense for it to last so long. With teh other 3 custom combo moves, you can get them so often. Yun and Yang charges their meter so fast, and it’s so short, so you get the super very often. V-ism also charges very fast.
With Juri though, it’s different. Her move is an utra, which means you have to take damage to be able to use it! (Focusing an attack still counts as taking damage since you’re putting yourself in danger) This means you can’t get 3 or 4, and even getting it twice is gonna be very hard. Because of this, she needs to be able to use it longer to really make use of it. If your’e Yun, and you get 3 or 4 geneijins in a single round, you basically won the match, because you can guarantee at least this much damage, even if you don’t catch them in a large combo. The same goes for Yang and V-ism characters to a smaller extent.
Juri doesn’t have the luxury of being able to do this because the ultra doesn’t charge as fast or as often.
So yeah, I think the main reason these moves are so good is NOT because you can pull off beefy damage with long combos, but because you can GUARANTEE some sort of damage. Messed up a shinkuu or a demon? Tough luck, it’s gone. With custom combos, you can keep going, mixup up until you get some damage in. If you get lucky with the move, you’ll get BIG damage. Plus, you don’t leave yourself wide open like you do with other supers.
