By character orientation, I meant when your character on-screen is facing right as player 1 and vice versa.
This thought came to me recently when I re-watched a couple of my own replays. I have the tendency to go to the left of my opponent whenever possible as I'm more familiar with inputting my buttons and directions from there. I mess up a little more when I do button inputs from the opposite end. This might be a potential weakness that future opponents can exploit, I don't know.
Are you more familiar and better as player 1 or player 2, or do you have no problems with regards to your character orientation at all?
