Well, if I'm playing somebody who has little or no experience with soul calibur, I ask them two questions.
"Do you just wanna play and have some fun or do you want to learn and get better?". If they say they just feel like playing around, I make sure not to pick Voldo.
If they want to learn, I then ask them if they want me to help teach them some things or if they want to just play and learn on their own. If it's the former, I'll usually pick a number of characters, show them some things and tell them what they should do to get around it, etc.
If they say the latter, that's when I just pull out the gimp and go hogwild on them, let them learn through their mistakes and offer a few constructive comments/advice inbetween matches.
Though, even then yeah it's usually dumbed down for two reasons
1. The reason we're (I'm speaking generally now, as in decent players, not saying I'm great) good is that we know the fundamentals of the game and, when facing other players who do, know that we have to outplay them mentally. We use a variety of moves and mixups because we have too, because our opponents won't fall for the same thing over and over. If the opponent *will* fall for the same thing over and over, then there is often little reason to use more than a couple moves and, in fact, trying to pull everything out of the bag of tricks is probably more likely to make you lose as we usually pull those moves out because we know that the opponent would expect/be prepared for the most logical moves and vice versa. You can't predict what your opponent is going to do if your opponent doesn't know what he's going to do, so sticking with the basics and what's safe means you win
2. Dumbing down your game makes learning easier for anybody you're trying to help teach. Learning through repetition is time-tested.
