Imagine a player giving a speech so powerful it rivals world class monologues. Just to roll a 2 with advantage, and EVERYONE at the table being disappointed.
If you KNOW moving in this direction produces the best story, you fit the narrative to what's most fun for players.
Critical Role's Brennan Lee Mulligan ditched D&D's dice in Campaign 4: no roll needed because a PC monologue was "too good."
Performance now overrides actual gameplay.
This isn't D&D. It's scripted celebrity theater pretending to be gaming.
They. Don't Really. Play.
