-I'd like to see point distribution go to a zero sum game.
My preference is to remove shootouts and go with Win / Tie / Loss = 2 / 1 / 0, I never found ties to be boring but I know I'm in the minority on that.
short of that, Reg. Win / OT Win / OT Loss / Loss = 3 / 2 / 1 / 0
-Remove the trapezoid
-I'd like to see the "puck over glass" penalty modified to either go back to ref's discretion or be challenge-able.
-I don't really have a probably with challenging offside or goalie interference right now, but if it becomes abused a little too much maybe the punishment for getting a call wrong is a "delay of game" penalty instead of losing a timeout
On the positive side, after thinking I would hate the hybrid icing I think it works great.
