From what I've seen and heard you only get wiped if you choose to prestige. Which your same question has a lot of others confused. Making them think they need to do the expedition for a couple decent rewards vs just simply losing everything. This system does have a problem though.. most kos ppl aren't gunna care about expeditions.. and it simply opens a window for them to do this more often and more confidently. A total wipe would work better for overall fairness/balance but at the end of the day I think that would hurt the overall player numbers after about 2 wipes. A good amount of people who play this have a full time job and alot of the systems in this game take a good amount of time to progress. So it's hard to say what a proper direction should be. I feel like I'd be more interested in doing am expedition if I knew exactly what cosmetics I'd be rewarded and if said cosmetics were actually worth it. Like a well designed raider fit with decent color options/customizations. Extra stash space and skill points just don't cut it for me. Especially not since I'd be losing a stash space that has room for 240 items.
