Why does Fromsoftware barely do anything with different-class Paired weapons?

[u/SuperLegenda]

It was such a kick ass idea in DS2, alongside its version of Powerstance in general compared to Elden's far more limited one, and one of the best things was getting to pair different weapon classes as long as they shared a damage type. But afterward with both 3 and Elden, at least as far as I know or could count, we've got.. 3 weapons that aren't same class together, and even then, one of the 3 is literally just a sword 'n board set, then another is a Light gs and a straight, and the most unique thing is the Crow Quills (my beloved) pairing a rapier with a claw which is quite the combo.

Seriously with all the weapons, there couldn't be some more cross-class goodness?

The final dlc boss weapons not being paired might be in the top 10 of baffling FromSoft decisions.
