I think 25 active quests was fair at launch.
We now have more than a decade of DLC/Chapter/"Season Pass" bloat.
10 more active quest slots seems like a very fair ask, to help keep track of any dangling threads we want to remember to circle back around to.
Also: things were on rails and level gated back then, and therefore it was WAY easier to avoid quest bloat.
I like the suggestion that daily quests could be tracked separately from 1-time story quests. That alone would solve most of my issues.
