Footlockers and caves will never be a source of rare top items because it's safe and easy thing to do.
You can get some from special enco, ok, but due to it's low rate of encountering you can't treat it as a solid source.
So far you could get (and you still can) countless rare items even as bleusuit from reno/warehouse.
I know there are places to get a bozar or PA, but it takes a group.
being a loner, "rare" items are "rare" now.
No, there are people going there alone and getting rare loot out of there. And I'm not talking about bluesuits now but people who gear up and go there ready to fight some small groups of enemies or in case of warehouse/v15 some npc.
If you wanna get do something alone - learn to fight.
If you are a bad fighter - get some friends.
You will not get free stuff for bluesuits after wipe (at least I really hope so).
