Nearly every big systems change in the last couple of years has just looked like power creep and homogenization to me, and most of the newer quests feel like they consist of groups of monsters standing around in the middle of a corridor doing nothing - unlike all the unique mechanics in older quests (although most of those unique mechanics are superseded by aforementioned power creep now anyway).
So fixing descriptions and typos? Yes, to me that's much more important than the Very Important Stuff - and I don't think it's just important for vets who groan at seeing the same typo or wrong loading screen for the 110th time despite bug reporting it once a year since 2012, but it's even more important for the new player who quickly realises that half the abilities don't do what they say in the description and gives up on the game because nothing makes sense.
Keep up the good work, and don't feel any shame about distracting other devs from the systems work if you need help on how to fix the bugs!
