Tell that to GRRR Martin.
And what happened when Jon Snow was supposed to die in the show...?
They killed off
one major character, early in the story. It put people on edge.
Once the story actually gets into the thick of it, random unexpected pointless deaths are no longer a concern.
Tell that to long-term fans of any sports team. Sure, everyone probably has specific favourite players at any given time but in the end it's always the team that matters, even if-when those specific favourite players aren't there any more.
Lanefan.
Are we invested in the story of specific players on an adventure?
Or are we there to look at literally 95% identical jerseys milling about the field?
The analogy fails because you've made it circular. You've
started from something that isn't comparable in the first place.
That's how I tend to look at D&D parties, particularly when I'm the DM.
The vast majority of people do not.
The look at it like a TV show, book series, film series, etc. If Indiana Jones dies 2/3rds of the way through
Temple of Doom and his place is taken up by, I dunno, Oregon Smith, his research assistant, people aren't going to give
Oregon Smith and the Last Crusade much attention, even if it shows her connecting with Henry Jones Sr. over their reminisces about Dr. Jones.
If people are watching DC superhero movies, they're
going to lose interest if you permanently kill off the founding members one or two at a time until all that remains are various B-listers.
This isn't like sports. People care about both the individual developments of each specific character, and about the two-person, three-person, etc. dynamics that arise between these
specific people. Trashing the character development
between characters is part of what killed a lot of the enthusiasm for the later Marvel movies, where they killed off developed characters only to replace them with alternate timeline versions that had zero character development.
Some of us like the challenge of trying again.
And your interests deserve to be included, supported, and respected.
But they don't deserve to be the only, primary, nor enforced thing everyone has to go along with. Design predicated on your way being the only way isn't going to fly.
Maybe the reason to keep investing is something beyond your own PC(s).
I do have that.
My investment in
the other players' PCs. My investment in the interactions these characters have with each other and, both individually and collectively, with their enemies.
That is more than JUST "noooooooo my precious bag of mechanics! My personal playthiiiiiing! How daaare you take it away from meeeeee you big ol meaaaaany!!!" That is genuine investment in the story, in
this group adventuring together and discovering who they all are and what they all want and why they all
care.
