What makes a combo look or feels good? And what's your favorite combos?
Whenever I use Sol as a training dummy in Xrd, switch control to record him doing something, I end up practicing various dust loops combos for 20 or so minutes, something about dust loops just make you want to keep doing(or trying to at least) them. I don't even play sol in Xrd.
In KoF, I decided to main Leona after seeing her HD combo, even though it's technically just a two special moves loop. It looks hype and charge buffering is pure joy. Games with long ass charge time are missing out on fun charge characters. I'd mention Hwa Jai's drunk mode, but that's not just combos, everything you do in drunk is so fun and satisfying.
In SFIV, srk FADC ultra was fun for while, and I still love doing Sakura's tatsu loops, even though I don't really play the character.
In Tekken, I'd say Nina's flapping butterfly combos look cool, but I've yet to do a single one outside training mode. ;__;
Speaking of which:
