Never. I hope the situation will force players to trade blueprints and "hunt" for them together etc 
And who will take this 1 blueprint found in 1/100 encounters when hunter party finds it?
Lockpicker doesn't need any party really.
Mostly "usless blueprints" (stimpak, needler etc) will be traded. Most people poweruse alts and won't sell good blueprints, because you don't know if you won't make a char that will need it. And you could look for it later for a month. It's very unlikely that you will see psycho or sniper rifle blueprint for sale very often. Which means peole who don't "abuse" alts are screwed.
I'm not saying I want them often, only that locks/traps could be possible to pick if you find them with "normal character", not one-purpose lockpicker alt made for farming from footlockers. And that they could be more often generated to fit the character that created the encounter.
Footlockers with strong locks and traps could have some additional goodies for treasure hunter characters.
Things that could be actually shared in hunting party, like caps or a few good items.
And they should have more enemies and NO "vs" encounters. They could appear only if lockpicker is with a group not alone.
Then you have your proper treasure hunting party.
