I had to reply to this one:
Q u o t e:
I have had the rather dubious pleasure of having to wait for over an hour in STV while some jerk running a 5 box of hunters or botting was grinding quest mobs. Refused to reply to any and all attempts at communication and just kept running around, killing everything that spawned before anyone else could get to them. They all moved identically, fired same at the time, in the same shot rotations, sent their pets out at the same time, etc.

In my humble thoughts, that did have a very negative and very real affect on my game play experience.
My response:

You get these jerks everywhere, not just in the multi-boxing community. I'm sorry that this person acted this way, but it doesn't mean all multi-boxers play like this. Don't look down on all of us because of something one multi-boxer did to you. Personally, if I see someone else questing in an area with a limited number of mobs, I'll come back later, or I'll stick to the big groups and leave the solo mobs alone. Doesn't matter if you're horde or alliance, I will not treat anyone like that.

So, please don't be so quick to judge the rest of us. We're not all jerks.
