Have recently noticed how different equipment requires different battlefield salvage to be upgraded. I shouldn't say noticed I'm just paying attention more as my pool of mechanical parts dwindle while other parts build up. For example long gun barrels should use way less mechanical components and have more weapon parts and maybe air frame parts. Last time I fired an MG or any firearm the barrel itself was a removable piece with no moving parts. I find several segments of my stockpile are growing while others get very low and they are being spent on equipment that shouldn't include them or at least not as much. I'm also just using gun barrels as an example. the formula for most items should be looked at.
I have read post where people dislike the whole concept. Overall I like it I just think its needs some tweaking. I would also like the option to trade salvage for different pieces.
Just a thought,
P.S. I really enjoy this game. I really hope WG can see a future for it again and carry on with its evolution. o7 all
