With the looting of armors on NPCs, you can actually get all the stuff you need through farming and PvE instead of crafting. Any stuff? No! You can't get your drugs! Especially now drugs are especially painful to craft (or not available at all for some). Even jet, the only drug farmable ATM, is very painful to find.
It's why I would like to see some NPCs encounters having drugs on them. For example, prospector and claim jumpers near Redding could have jet, hubologist near SF could have mentats, mobsters, yakuzas and gangs near Reno jet and/or buffout, BoS and anklav patrols could have psycho and/or buffout on them, same for NCR army which could have few psycho and super stimpacks. All caravans could have cigarettes, beer and nuka cola. Those are just examples of course.
Second things, there are some weapons/armors which are simply not farmable at all, which is kinda sad, especially now that many encounters are harshers. For example, since plasma pistol have been replaced by rifles at anklav to get them stronger (it worked ;p), some mercenaries/hubologists could get those. Improved flamer with fuel MKII could appear in the hand of NCR caravan/rangers instead of regular flamers. P90 and pancors could be given to various NPCs instead of assault rifles/HK caws. For armors, tesla and metal MKII could appear for some encounters (I know enclave and brotherhood armor will eventually be added too, why not improved versions of metal).
Last thing, anklav and brotherhood don't drop their armors for pretty obvious reasons. But I think making them drop their armor automatically beyond repairs to allow to gain few HQ ressources by dismantling them would be a nice little bonus (support perk "power armor skinning"?

).
So, what do you guys think?
