The current way is fine the way it is. I mean when has the current system ever screw over a deserving playoff team and let an inferior undeserving one in instead? I can't think of any that jump out at you. It's not like we have seen a 42-37-3 team miss it while a 36-28-18 made it instead. In that scenario a team that won more games then it lost would miss the playoffs while a team that won 36 games and lost 46 made it instead because of when it lost 18 of those games. Nothing that far fetched / drastic has happened and therefore it really isn't a big deal.
If the NHL really wants to shake it up, we can keep Ot and SO but a loss in either just counts as a loss. The other big 3 don't have a points system and they seem to be OK (aside from a division winner with a losing record making it over a 10-11 win team in the NFL or a 37 win team making it in one conference and a 45 game winner in the the other missing it in the NBA every once in awhile)
And since we are talking about records, I do not consider a team that goes 35-32-15 a team with a winning record. Technically they got more then 50% of the available points but at the end of the day they lost 47 games and only won 35.
In my eyes you only should be considered having a winning record if you have 42 or more wins in a season in today's format since every game ends in a W-L. The old way was different because winning less then 42 games could still leave you as a winning team because of ties. Plain and simple , more wins then losses = winning record.
