It can take a while. But you can max everything to 99.
For Technical, try setting the difficulty to Legend, set the balance options so that the A.I. counter a lot. Then throw your CAW on a 1 on 1 match with CPU vs CPU and just rematch when it's over. You can raise it without having to do much. If you have two controllers, you could control both as well.
You basically want to do a lot of counters when it comes to raising your Technical.
^ I've got to try that. I'm getting annoyed with having to constantly having to play the same kind of match over and over. It would be nice if they still had the ability to assign AI to your edits. Then you could just constantly put them on the advantaged side of a handicap match (would work for everything but Technical).
