I agree with Manon - if you have a good perimeter defense, 3-2 zone is actually better than M2M. It's one of the few cases that zone defenses actually work better than m2m :)
Patient is an interesting offense. I have used it with some success, however not on b3 level and especially not on pair-to-pair matches. I wonder what happens if you have a very high player in JS, JR, DR and IS, would that make Patient work better than any offense?
The answer is no. Simply because Patient is easily stopped by high OD.
