Right now, the answer is that the devs have their focus set pretty much completely on WoM, so anything non-critical has been pushed aside. In general, the answer is harder, but is still more than likely a question of where the focus of the devs is.
For some things, band-aid fixes are indeed useful, but they’re things that have a huge impact on gameplay or its variance. It could be argued that the shields’ general condition or Zealot’s strength, together with his weapon options have that kind of impact and should be addressed in some way ASAP, but it doesn’t seem like the devs think so. Game-breaking bugs are also something that could warrant a workaround before a true fix is implemented, but I don’t think there are any that most people would consider as such in the game now.
For anything else, band-aids aren’t a good thing. They’re likely to raise some ire from the players, and create more work later on. While setting some numerical values is indeed (probably) easy, finding the right numbers isn’t, and requires enough fiddling that a more permanent solution can be equal amount of work. It can even be the permanent solution, after some fine-tuning. Also, not everything can be addressed, even temporarily, by simple numerical fiddling.
I agree though in that some of the unbalanced/non-working things (several Talents, including BH’s, Handmaiden’s and others’ lv25 options, for example) should’ve been addressed a long time ago, as they effectively reduce our choices significantly (either through some options being useless, others being too good or both). I sort of understand that manpower and working hours are limited, but these are things that have been complained about since practically the release, so there’s been a lot of time to address them.
