guys,just a small opinion,but,i think is not random.With a substantial number of accounts,i found out that smaller(by exp and gear) accounts have a higher chance to get Ship designs/LF4.The content of the box changes from a player to another.How is that?Think about the ones that have full 2 apis build.They don't recive any more apis parts,but SOMETHING else instead.Also,i have quite a number of friends that have full LF-4 and they keep getting them MUCH more often then they used to before they got full LF4.So that's my point of view:If u have an equiped ship you will have a lot less "luck" on LF-4 and ship designs.
I think the chanches are higher in the PvP maps (4-1,4-2,4-3) Atleast it was in my experience
2 free booty keys from BugPoint=Sentiinel and Vengi EXP desing on 4-3 lol
plus few LF-3s on the same map i dont rly buy booty keys much.
I suposse it's cuz in other maps there are aliens (ofc) lol and they leave booty after they got staken down,and in that booty only useless things are findable -.-
