it's almost like the fanbase is split in two.
who cares about regular season wins/points.
I think you're reading a little too much into it.
I'm going to say something controversial on a forum with diehard fans and antifans. I'm going to say something that will likely have my word twisted down the road, but here we go.
Most fans, even on here, do not tie their personal happiness and success to the success of the team. They do not require a Stanley Cup every season to get on with their lives. Most fans watch the game as a distraction from other things, or a way to wind down at the end of the day. The entertainment that comes from the success is appreciated, and those fans certainly would
like the team to win the Cup, but sometimes watching their favourite team is just an escape, and having a competitive team in the regular season make that escape enjoyable and it goes on much longer through the long winter months than the playoffs do. Some people want that regular season success so they can enjoy cheering on their team in those evenings, and they would like their team to go far, but when they're eliminated, that sucks, and they move on with their lives understanding how stacked the odds are to actually be the last one standing in most elimination sports tournaments.
The slightly more advanced understanding, but still pretty layman understanding, is that usually good teams do well, mediocre teams do okay, and bad teams do poorly. So yeah, of course you root for your team do well in the regular season with the implication being that they are one of the more competitive teams and it will better their odds in the post season.
To actively root for your team to be middling and squeak in on a wildcard spot, expecting them to finally become competitive and win the Cup is certainly not a "route one" stance.
So, yeah. A lot of fans here do want to celebrate and see regular season success. But that doesn't mean they don't
want to see post-season success or they want the regular season success to be at the expense of the post-season, in fact, 99.9% of the time the desires go hand-in-hand.
I don't see how wanting regular season success could ever be framed, in good faith, as a bad thing.
