Wow, very.
I was on two days ago, just picking plants for the survivalist achievements in free roam, and some douche bag Mexican on a donkey comes up and stares at me. I wait a few seconds, and when he doesn't speak or draw his gun, I go back to picking plants.
Of course, he shoots me when I turn my back to him. I respond by killing relentlessly over and over for the next 30 minutes. Then a friend of his gets on, and tries to help. He sucks even more than the firs guy. I just spend a good 15 minutes killing them both as soon as they spawn, to the point that they had stopped firing at me and just started trying to run away. Sometimes I would let them climb on their mount, and then shoot it out from under them before finishing them off just to toy with them. They eventually logged off.
Stupid newbs didn't know who they were messing with.
