They’ve definitely gotten a buff. It happens every time they make a change like this. When 1.4 dropped you could pull aggro at one side of the library and still run through with minimal flange. Then it slowly started to change. They weren’t necessarily hitting harder, but their accuracy was spot on and they would focus fire you.
I feel like the NPC have been modified again. They move faster and are somewhat strategic. I’ve been running Stolen Signal and I have to say, curveball’s accuracy with those nades is dumb. He doesn’t even raise his head when he throws them. I hit him with Flashbangs, his arms are in the air while he’s blinded, and his bases still manage to land exactly where I am.
