-Nightmare enemy only levels having a special message can be nice, but I'll note it's proposed to give them sounds (+ sounds to all the silent bosses too) and it has been discussed in the Discord, due to it seeming unintentional and the current modding grey area that exists with modding them in sounds yourself like I do (Kornel also mentioned he forgot to give them sounds when adding all the new Nightmare enemies).
-I wouldn't oppose the Acid Spitter reloading faster, but it ultimately wouldn't matter, as it's not a weapon you can reload with enemies around regardless, whether its reload time is 1.2 seconds or 0.1 seconds (reload time only matters when you got an enemy in vision/pursuit or some time sensitive event is going on). In any active combat scenario, you get one shot with it, and then you have to wait until the immediate threat is gone before you can get to scooping the acid back up.
-Yeah Enviroboots aren't great for plasma protection (only reducing blood damage from 12 to 9, 1 more than unmodded Plasteel Boots), but as mentioned in the Discord, it doesn't affect their usage that much; in A100 you're still building Cerberus Boots regardless, and in the standard game, they'll be virtually identical except with Enviroboots being worse for Limbo and the rare late blood cave but it won't require the massive mod cost that Cerberus Boots does, making Enviroboots still a very valuable find. So I would be ok with Enviroboots getting that plasma buff, or keeping it as is to give some extra flavor difference between them and Cerberus Boots.
1. Very interesting. Probably wouldn't be opposed to it, but it feels like it'd be a bit of a shock after all these years of silent Nightmare enemies. Even if the line changes though, glad to hear you do think having a feeling for it could be good.
2. Fair enough. It just seems like adding something unnecessary on top of it. It's a shame that it's so unwieldy since it's really fun to use.
3. I agree that some differentiation is nice, just feels like kinda unfortunate when you finally find it and there's no reason to pick it up ;_;

Having said all this, I think I'd like to bring up a topic that we've talked about before on the server.
Crates should be buffed/diversified, especially for late game.Their utility early on is somewhat nice since you can find an armor or boots here or there, with the obvious prizes being ammo boxes... but their utility drops off as you advance along the game. In later levels you're not likely to find much of anything of use - if you open them in hell (or Beyond, for ao100), you're likely to still be getting just green armors, bullets, the occasion steel boots.
I'd like to propose that as levels increase, you can find other stuff that could be useful in the crates. The main idea would be plasma cells and rockets (their associated ammo boxes too maybe?), although there's plenty of other stuff to consider - medkitz, maps, phase devices, red armors... could even consider a mod pack here or there. This is without even considering if any uniques could have a super-low chance of appearing.
Crates are funny to blow up and see what goodies may be inside, and replicating that feeling beyond Phobos seems like it -shouldn't- be that difficult. It'll help add some more variance, and IMO shouldn't be too problematic, especially since in later levels a lot of enemies are prone to just destroying them along with any goodies they may contain. So it sets up its own sort of minigame of how to approach and dodge/tank if you want to try to open up the crate without the given enemy destroying it first.
I know stuff like exotics and rare mod packs are off the menu (maybe in Ao666?), but even with what I've mentioned above it feels like it'd improve the treasure hunting experience, so to speak.
