I have bad news for those who hate ties: The current system does nothing to reduce them. If 60 minutes of real hockey ends in a draw, you've just watched a tie. In fact, tie games happen at least as often as ever. What happens after those 60 minutes – a contrived 3-on-3/SO contest – doesn't change the results of the hockey game you spent two hours watching.
Yes, OT/SO gives you a result, but it doesn't tell you which team won the hockey game, it just tells you who won a 5-minute contest. OT/SO is like 'kissing your sister' – you couldn't score during 60 minutes of real hockey, so let's engineer a fake way of getting a "W".
If you sincerely believe a regular-season OT/SO gives you a legit "W", then why not have it in the playoffs? What's the point of watching playoff overtime, which feels like an endless tie, when we can skip ahead to the result you crave?
