The rules can be tweaked over and over again, but the real issue is goalies are bigger faster stronger with lighter better equipment and the dimensions of the net are the same.
This is the answer. The problem is advanced stick technology requires advanced goaltender technology. Simple fix is to go back to wooden sticks but that won't happen.
That would be the answer if the problem was goal totals, which it isn't in my opinion. It's the lack of scoring chances, and that relates completely to the role of skill in today's hockey. I feel like skill, both defensively and offensively, is stymied by tactics employed by teams and player that is pretty much against the idea of the rules.
Now I'm a fan of defensive hockey, I love watching defensively skilled and smart players do their thing. That is another reason why I dislike the development, because defense today is less and less about actually being skilled and smart. So many teams and players out there get away with not being skilled and smart defensively by employing tactics that should not be allowed, such as all the interference going on.
Teams like to set up a bulwark at the blueline, forcing the dump-in. Then they'll crisscross in front of chasing forwards in a manner that would be interference ten years ago so they can't get the puck. By far the most effective ways to defend, taking away zone entries in both ways. If those interferences are called, teams need to use more depth to defend the dump-in, opening up for carry-ins. Result would be much more controlled zone entries, one step towards making it a more skilled game.
The goaltenders rely on skill less these days as well, but that's a lot due to size and you can't really do anything about that. Now I don't really care if they make a lot of saves, I wouldn't care if goal totals increase at all.
What I do want to see is more scoring chances, a more important role in today's game for skilled plays in either end. To achieve this I think the league has to take a hard look at what being a good, skilled player means and then shape the game to fit these players more and fit unskilled players, who make up for not having these qualities in other ways, less.
If this was a league that had few scoring chances because players had become so good at reading the play, picking off passes, win 1-on-1 battles and steal pucks etc, I wouldn't say a word. But I feel like there are few chances because players get away with a lot of interference, holding and other things that's not about them being defensively skilled or smart.
