Last night, I got disconnected while on a server. It doesn't happen to me often, but when it happens it can really put a dent in my supplies. This time, I lost 3 wraithballs, 2 ballastballs, 2 anchorballs, 2 wearyballs, 1 helmball, and the standard other stuff.
When you get disconnected so that the game saves you a spot for 10 minutes, it should also hold your inventory until then. When you rejoin a game, you get your stuff back.
In the past, some have had ideas that when you leave a game, you leave behind a bag of your supplies. That could work too.
I don't think I should be inclined to leave my best supplies in the barrels for fear of it being destroyed by getting Rare'd. Especially for PvP, and especially for items like wraithballs that you don't want to get stolen.
I'd assume that this wouldn't be very hard in terms of development, the game keeps track of your supplies during the whole session, an extra 10 minutes wouldn't hurt. At the very least, leaving a bag on the ground shouldn't be hard to make either.
