It seems pretty clearly obvious if you go through the CS and keep the names of the particular affects in mind that they should have been added.
I already went through the CS, and I still don't think that it's a case of they "should" have been added any more than that they used to be used and then were removed for balance purposes (or some other design reason).
I mean, put another way, there's plenty of content in the CS from stuff that never got implemented in the game. I mean, the glass Arrow of hexing is still currently unused, the pit armour isn't used, there's a bunch of dremora armour not used, a blades shield, some "Ghost dog" gauntlets, the rusty iron gauntlets aren't accessible (seriously?), a bunch of other magic armour, a variety of handbills, the level 5 version of Cruelty's Heart, leveled versions of the Apron of Adroitness, a bunch of enchanted jewellery, several creatures (and yes, I'm ignoring the ones marked "TEST"), such as the two kinds of "dark broodling", heaven only knows how much dialog that got made and never got used, whole reams of enchantments (and I've used some of those myself when I was making the enchanted equipment for armamentarium), a rice plant, plenty of grass types, the durable silver warhammer, the nirnstone...
Do I need to go on?
Some of this stuff has
obvious placement options, some of it doesn't. I'm good with your change to the dark guardians because I've never had any problems with them either way, if you think that it's intended for the player to be able to walk out the tutorial dungeon with a full set of armour then, well, no big worries either way.
But adding two sets of resistances (but strangely, not a third) to creatures which will have serious changes to the balancing of those creatures. I am just not convinced that this falls under the UOP and not something like MMM or OOO. I can see people who use the patch and not other mods getting confused about why the UOP is "fixing" something that's in no way broken.
I'll probably stop just now, I've no wish to beat on this, and as I said; I actually *like* the idea of imps having magic resistance, I just don't think it's the UOP's job to add it.
