As of now, it seems the only way to guarantee you won’t be penalized is to stay a good 4-5 feet away from your opponents platform in the last 30 seconds.
at first this seems obvious, and a sensible thing for teams to do, but in a swing game like this, there’s often a choice between risking an <sg3> penalty by coming near the opponents platform to steal a few goals or something, or just sitting on your side for 30 seconds and doing nothing. Neither are good things to do. If <sg3> wasn’t so harsh with the penalties (no penalty for non-gameplay affecting contact, maybe only a give dq if the contact was match affecting) the game would be a lot more fun to play in the last 30 seconds, and referees would have a so much better time not having to determine the outcome of several matches based on a brief, subtle interaction.
