I recently tried playing as a single rogue and would attack enemies in a stealthy manner with a bow. I'd plink away at a group of 4 enemies, and they would just stand there and take it. They know they are being attacked and talk to each other indicating they know someone is out there, but that's it. This of course is common in many games, but based on other interactions I've seen in the game I suspect they could do better. Perhaps move to take cover, or in a large settlement, move off to raise the alarm, start patrols, etc. WIthout this I can pretty much just plink away very carefully the whole campaign. I knocked out half the Druids' camp doing this, and enemies 20 feet away from ones I kill are standing there like nothing is out of the ordinary. Hoping this will be improved long term.
Love the game by the way.
