Ahh, see I play w/ the same layout I've been rocking since SNES SF2, which uses L+R for Strong and Forward. So L+R is my swap/tag. However, it does seem to miss the input sometimes. Same thing happened for me on PS3, though. I always thought it was because there was some element of the game I missed.. like how you can't tag while getting hit, I thought maybe there were other rules as well? As far as special moves go, the controls are fairly good, though I whiff at times. The d-pad on the Vita is pretty great overall, though.
