Hey, I've been lurking for a bit around here and this post made me want to reply.

I've definitely noticed that players on both factions treat me a lot differently then when I was playing solo. In PvP situations people love it and I'll get whispers like "hey that's fckn awesome!" and horde will go out of there way to gang up one me or camp me if its not in a BG. Little do they know that whenever they camp me I have a secondary fivebox squad to play. While they hover over those corspes for 10 mins, I'm already inside an instance getting more XP

However in normal questing and PvE people aren't as cool about it. I've gotten plenty of "you must have too much money" or just "you're retarded" comments. Fortunately the accusations of botting and threats of reporting have been few and far between. Seems most people on my server know the difference between a boxer and a botter.

The previous replies regarding basic human psychology are right on the money here. Especially when it comes to the teenagers.

Most hillarious whisper so far: "IT LOOKS LIKE YOU DOING SOMETHING IYOU DONT POST BE DOING"
