My idea: interact with any of the spawnpoint striders in Freeplay and be able to enter them, change javelin, access the forge, and cash out your item drops without leaving Freeplay. Most of the time I end up leaving a bunch of items, depending on how long my team is planning on being there. It would be nice, in my POV, if I could loot everything and then just drop it off and salvage when my inventory gets full without leaving the map.
That could also be a store item idea, let you customize your strider interior with furniture, paint or other decorations.
The strider access functionality is already programmed and made in another part of the game I think. With forge/expedition access via your own javelin even.
