I think aggressive is a weak word for it. Ridiculous might be more accurate. I was going through Becket's Quarry, and not only did 6 things lock on to me, they didn't even bother to follow me. They just stood where they were, hitting me with apparently magical cutlasses that reached through rock and over several yards. I know because I had to hunt them down and kill them before I could get back to what I was really trying to do.
This is not cool.
And btw, I want my old weapons back. The three I have so far ( doll, pistol, and cutlass) are ugly. We need an option to change weapons, like we have for clothes. Do the quests, get them all, then use the one you like.
I'm liking this less and less.
