I did a zone in Green Plains, and it was a security. All I got out of it were some uncommon weapons and a few other misc components. I know you aren't supposed to get like a unique every time, but after dealing with constant hordes that tested my two high tier rpks, a golden liberty, warbringer, and a tmp, all with good gear (uni holster, melee exo suit, uni armors, and a swiftdraw) and an elite infected (a herc riot infected, now that was an interesting fight), it was a tad disappointing to only receive the same amount of loot (if not worse, honestly) that i'd get by running that same mission again.
I think with a few tweaks in terms of loot (maybe some high activity zone-only stuff?) and infected counts, this would be an extremely fun and useful addition to the game.
Still good as is, but it definitely needs rebalancing and tweaking.
