I've played pad as long as I've played fighting games (and games in general :P) and haven't had too much trouble learning difficult things. I main I-no in GG and can chemical love -> airdash about 75% of the time.
After a bit of practice, tech hitting doesn't seem to be too hard. I roll my thumb over the face buttons as well as hitting one of the shoulder buttons (hitting both shoulder buttons feels awkward). That's 5 buttons which is 90% if I read correctly. I play lilith so the hardest thing for me is comboing into LI. I may try to get on ggpo if I can figure out that port forwarding stuff.
