@Noelle808 I watched my roommate work on those Yuzu dash-B/C hits for the better part of an evening–the timing definitely takes some getting used to! I tend to prefer double-tapping the stick for dash attacks in combos too (Eltnum’s run and gun especially). Helps me not get my wires crossed on attacks vs movement. I’ve found the A+B dash to be most useful for short controlled movement, like dash-blocking towards a zoner, or dipping in/backdashing out of range to bait an attack.
Speaking of combos in general, Unist was my first real ‘combo based’ fighting game after mainly playing Smash and PM/watching other games at Evo each year, and it was interesting how much learning combos reminded me of practicing an instrument. Feels like a lot of the same techniques for learning apply, like breaking longer strings down into chunks and finding the physical rhythm. Also definitely has the same sense of frustration when a line won’t come together, followed by satisfaction when it finally clicks (especially when you then pull it off in game).
Outside of the in-game mission mode, another practice method I’ve enjoyed has been watching videos of pros at 75% speed to identify patterns and combo segments they use a lot, then trying them out on my own. It’s a nice way to identify smaller little segments you can work on and improve, when some of the Veteran mission combos can get pretty intimidating. Kurushii Drive does a great job of compiling highlight videos of various characters/players on youtube!
