My understanding is weapon drop perks are random where a one perk has the same chance of dropping as any other, or at least that's how I think it should work. That is not what I've seen especially lately. I had another post complaining about how painful and frustrating weapon farm is now without crafting. I prefer crafting but OK with farming if each perk has the same chance of dropping. I've been farming chroma rush, gridskipper, nox smg, dawning weapons and amazed at the number of weapons I receive with a few of the same perks, none of which are what I want. I haven't farmed this weekend but did all last week. I forget what weapon kept dropping with to the pain, heating up, desperate measures. It took 3 full 10 hr days of farming Chroma rush to get kinetic tremors and only 1 subsistence yet I received an over abundance of to the pain. Then mostly got extended barrel/extended mag and hardly any arrowhead break/accurized rounds. I've posted this before questioning why I only want that or the other perks are good. I appreciate the comment and looked further into what I've been deleting. However, they may be good perks but I'm mostly frustrated with getting an over abundance of some perks. So my question is, are weapon drop traits/perks random or is there some level of acceptable weighting to avoid what crafting ends up with some perks mostly being used?
