Going to a three point system has been mulled over for years. I think switching the qualifications to make the playoffs should be changed to the teams that have the most ROW. This eliminates the shootout as any kind of deciding factor for teams to get in, and has no effect on standings until a tie. Points would be a good secondary tiebreaker. I always thought GF was a bad tiebreaker, does't seem fair to defensive teams. I would be fine with the season series used as a tiebreaker, or even goal differential.
For the record, I personally think shootout is better than a tie. Changing to ROW would keep anti shootout people happy, and keep the shootout in the game with less weight.
