lol combos aren't that hard on a stick, and super jump cancels are actually easier. It's the finer details, like being confortable with diagonals (i.e. blocking damn overheads), IAD and general movement and spacing.
That said, it just feels too badass to tap the buttons on a stick xD and since I despise mapping several buttons to one on controllers, doing RC is always a bitch with just my thumb >.<
