If I can throw in a wish it would be to actually tighten up the combat, like in SCV. This feels more like SCII, where the hitboxes seem to actually push the opponents forward, rather than go through them. This is pure preference, and I know most prefer the feel of SCII.
Combos feel less like combos now, and a lot more random. I was never a fan of range affecting combos, but now it's more random than ever. Raphael is a good example of this. Close up Prep BBA+B will sometimes give a wall splat, sometimes veer off and sometimes not move at all. B4 against the wall does at it pleases, and launchers like 22BB give time to react, but still feel iffy at many ranges.
I don't remember this in SCV. Everything felt... Tighter? Characters like Viola would never exist in SCVI's hitbox engine. All consistency would go out the window.
Writing this out though, I'm already disagreeing with myself. It seems what I want would involve an engine rewrite, and people hate on combos now-a-days. I have to say, the feel of the game is 90% what I want, and my main never had such long combos till now. It all just feels slightly sloppy and loose.
I think there's probably only a handful of people that will actually get what I mean, but I will insist that consistency is very important for a game to gain respect in a competitive setting. I'm not talking Tira personality consistency, more what a viewer can predict will happen based on what they've already seen.
The current system has a higher skill ceiling, because players need to react on the fly, but it hurts the viewers. I will stress the importance of SCVI's watch-ability as integral to it's marketing outside it's player base. It's 2019.
