It's not just opinions, it's actions. One hypothetical group maybe has a SS or GWM in it, and they dominate in straightforward race-to-0-hps combats, but the DM brings in enough other situations and challenges that each other PC also has his time in the sun. The DM did something to fix the problem - he may not even have recognized the problem, specifically, maybe he just noticed that some PCs were doing a lot and some others were doing less, and put more situations that called for the latter to do stuff in their way.
And what if the group or the DM primarily enjoys "race-to-0-hps combats"? What if
the module essentially only features race-to-0-hp encounters? It's not like dungeon crawl modules magically went away when 5e was published.
Are people who enjoy playing this way just not supposed to play the game? Are they not supposed to play with optional rules because, God forbid, they change them to their liking? People are supposed to completely alter their entire table, their entire DM style, their entire campaign around optional rules that they want to use because
one of them of many makes them unhappy?
Why is it superior to fix the issue by warping the entire game around one rule instead of
just changing the rule that appears to be causing problems? The Player's Handbook is not a suicide pact!
I mean, we have people here saying things like this:
"Is the issue that DMs can't handle the damage this feat deals or that other players 'might feel upstaged' by the feat.
If it's the former the issue doesn't lie with the feat. If it's the latter, the issue doesn't lie with the feat.""
Which is just explicitly saying, "You're playing D&D wrong and it's your fault." How is that not offensively condescending? "Gee, if you could DM your way out of a wet paper bag you wouldn't have this problem." I mean,
seriously? No. That's not fair. Stop gatekeeping my DM style. Stop gatekeeping my campaigns. Stop gatekeeping my house rules. Stop gatekeeping my table.
