So I started to notice I was spending more time shopping for gear than actually adventuring, and realised it was down to the poor scaling. So I installed the "No Scaling" mod, and it's exactly what I think all RPG developers should be looking at implementing.
For example, Witcher 3 could really do with an equivalent mod to make gear remain relevant throughout the game's duration and allow for more options instead of being made irrelevant when levelling up.

While it has made DOS2 a much less interrupted experience, I do worry it's broken the difficulty, as most encounters now seem relatively trivial (it could just be that I all of a sudden got REALLY good, but I'm guessing not!). However, I would assume that to make encounters remain challenging while removing scaling would require a more extensive pass over all of the potential fights in the game, and this is probably too much to ask of a one-man mod team.

But even so, as proof that scaling systems really aren't needed in RPGs, it's really reassuring.
