As long as you are only make small changes at a time it should be fine. Bump it up, play 2-3 games to get a feel, then evaluate. The problem that happens is people make lots of changes and then things get out of whack and they don't know what caused it. These sliders this year are very sensitive. That's what's great about this approach. Things have been brought down and you can slowly bump up a certain area if you feel it's lacking. If it doesn't play right after the change at least you will know why and can try something else.
