I've mostly been grinding world tour, but starting to play ranked. I don't really have a lot of fighting game experience, but I've managed to work my way up to silver so far, and still climbing.
So far I've been using Luke with modern controls. Haven't learned any combos yet, mostly just trying to focus on fundamentals. It's kind of funny when I beat people who have clearly put some effort into learning some big combo, but they don't know how to block, or just let me keep anti-airing them. Once I get to gold, I'm planning to start trying new characters and figure out who I want to main.
