you gotta know people or check recruitment pages play in a beta tribe for awhile and hope the alpha tribe takes you in after awhile. its not easy to get in to alot of the bigger tribes
exo mek can have 600 slots and noglin can carry 300 so maybe your noglin was slot cap on light stuff that is why but if its full of heavy stuff will still work
i did videos about this 6 months ago to just had the clips recorded because this is how i started on 1x and i got a shit load of loot so felt like showing everyone how easy it is to get loot with a noglin
