Welp...until you put proper value on a win, it matters littler how OT plays out as it is a bit of a sham as is. Matters little what you do in OT or how you play it as the point structure now is. Would be a big difference how many teams play out the last 5-10 minutes of a game if they lost a point by not winning in regulation...and wold make the season more exciting.
Essentially, as is, i do not have to win in regulation to get 2 points = a bit of a sham, whether 3 on 3, with re-setting, not re-setting, shot clock or or shoot out.
