If what you remember later when telling war stories is that Danegald and Bezekta once got into a heated rivalry that eventually ended in a duel, does it matter during which adventure this occurred?That's seems... I dunno. Odd? It doesn't make a difference at any moment of play if you're trying to restore the Ordning or if you need to defeat Strahd or if you need to end the death curse? This statement is very strange.
If what you remember later when telling war stories is that Carantha and Jerelle fell in love and, later, got married, does it matter during which adventure(s) this occurred?
If what you remember later when telling war stories is the legendary Battle of Three Tents* during which the party - attacked by a patrol while camped at night - destroyed all three of their own tents, one MU killed two orcs entirely with her dagger, and the other MU's only contribution was to drop a telekinesed boulder on to another PC by mistake; does it matter during which adventure this occurred?
In all three cases the answer is no. And 9 times out of 10 those are the sort of war stories that get told, at least among our crew.
* - an actual combat - in which my namesake here (Lanefan) was the PC who ate the dropped boulder - that happened in 1984 and that we still laugh about today. The DM probably remembers offhand which adventure we were in at the time, but I doubt any of the players do; I know I have to look it up in the game log every time. But we sure remember that battle!

Why, might I ask?Nope, hard disagree. This goes next to the printer.
If I'm going to play 1e, it's in spite of things like this, not because of them.
I know for my part it doesn't matter if every member of a class uses the same underlying mechanics, because what matters more is the personality and characterization you layer on top of said mechanics. And why do those matter? Because P+C are what makes a character entertaining to the others at the table. Mechanics don't.
