I'm pretty much the same way. I wouldn't mind doing instances and raids if people were courteous and telling me how to improve in a nice manner. People wonder why I'm not so good at something or know a fight--its b/c when I try to do a PUG, I get yelled at and just leave to avoid annoying people.

Pretty much. If I see a horde or anyone killing something nearby, I try to help if it looks like they need it. Doesn't bother me. Battlegrounds are okay to play, but I don't play those for achievements b/c it'd be impossible for me most likely. AHHA.
