It's not just the sacks for me.
It's mainly the constant overuse of just a few plays with no significant repercussions for the offending team that bothers me the most, combined with people playing CBs on the DL (for example) simply because "it works" in the current code since weight isn't much of a factor, etc.
All of these items are being addressed in testing right now. I am still hopeful the changes will be meaningful and not just lip service. If the next version doesn't take care of these issues, I'm probably out.
