It would be really awesome if they could have different variations of enemies have different behaviors, for example have the chameleon deathclaw stay quiet or not show up on the [ CAUTION ] and make the AI follow you for a while before striking, maybe it will stalk you until it gets close enough and then it will rush in and try to insta kill you with it's grab? or maybe it will attack when you go to sleep? have certain raider leaders have perks like Paintrain and Rooted? It'd be pretty cool to go up against a legendary raider expecting to smash his face in only to be disarmed to my fists or how about getting charged by a enemy in power armor etc.

That sounds like a lot of fun. I would enjoy if that were implemented as a feature
