In general, the Raiders drop very, very differently in comparison. Armors are very rare. Not a single Level 5 or 6 Armor dropped. Weapons are weaker too.
Amor: 90% or more dont wear amor. Not a single armored rig. I got a few class 4 amors (mostly the new bad lvl 4 amor with 40 hit points).
Weapons: SKSs a few, many MP5, Many Vektors, one MK47 (new US AK), Many AKs and AKUs, not a single M4, one RSS
Ammunition: Best Amor Pen i found was 7.62 BP. 5.45 best was BT.
Healing items: I noted a very big change here. I got almost no healing items anymore. Pre patch you got bombed with IFAKs, that is over. I got maybe 2 in total.
Grenades: definetly less grenade drops. Down from 3-4 per Raider to 0-2.
Bagpacks: not a single Attack back pack, mostly the new ones. In general smaller ones are way more common.
Rigs: Mostly the new ones + thunderbolts.
