With teams regularly playing back to back playing endless OT until a winner is decided is just stupid IMO - the risk of injury instantly goes up.
Alternative could be 3 points for a regular win, if it goes to OT the its 2 for the win, 1 for the loss, so the game becomes less valuable for everyone involved.
I feel like in the past people have looked at the standings with different point variants and it usually doesn't change things too much.
As everyone has said, you got 60 minutes to beat the other team, then 5 in a higher risk situation with loads of odd man rushes, after that you just need to put the game out its misery and get the f*** home so you can rest up for the next day. With 82 games in the regular season they're just not valuable enough to do anything more than that IMO.
