I'm gonna give the AI a look, just to see if there is anything I can do. No promises though. I've considered removing the ranged ones for now, but we'll see. I might just dilute the entity group so there's way more melee ones.
The Vault is a T5 quest, as is the behemoth POI.
The laser shotgun/AEP: There just isn't a better way to do this right now, without code. It's basically setup like a bow that fires 8 arrows at once. There is a way where I can make it a normal shotgun that emits the laser particles when fired, but I feel like that wouldn't feel right, or look that good. And I want their ammo to a bit hard to get early, so that's fine.
I haven't tried using dye on power armor. Does it not work?
Weapon mods...we already discussed this. Lol.
As for the future? Hmm. I have a few protectrons I've been slowly getting ready to add to the game. Also have a nightstalker type creature, and a rad scorpion of sorts. And I have plenty of POI ideas, like the Super Duper Mart and others from Fallout. But those are a major time sink for me as I may have a bit of OCD so I always spend a lot of time on them. Haha. And there's always more items and stuff I plan to add. Some of the drugs from Fallout, and new foods. Maybe some notes to give small quests that lead to legendary stuff. Maybe a legendary set of power armor?
I've been on a bit of a break lately, mostly just playing some ARK. I've added a few more vehicles to the Wasteland, and tweaked some stuff in my AIO mod. I plan to push those updates at some point soonish. After that, I may hold any new stuff till a20. Definitely won't be doing any more POIs till then, from scratch or vanilla ones.
Hope that answers your questions and glad you enjoy the mod.
