Braden, there's a difference between teaching people how to PvP and suffering deaths and defeats because doesn't atleast do some basic preparation for the activity they're about to do. I'm not a hardcore PvPer, I made a PvP healer mainly to fight for my server's Tol Barad and to get a few random BGs in every now and then. But I can't tell you how many times I've had to hit my head onto the desk while watching people wearing not a single piece of resilience gear completely weigh down the rest of the team. I can keep people alive fairly well, but when that Paladin over there might as well be wearing paper, there's only so much I can do. Just as bad is when the team is made to look like fools because half of the group can't understand basic concepts of group coordination and awareness of your surroundings. In other words, it's not very helpful when a handful of people stop to fight on the roads in Arathi Basin, or run in one at a time to attack the opposing flag carrier in Warsong Gulch. Someone will try to point out what they're doing wrong so that they can get in line with the rest of the team, but they're so focused on just getting kills that they don't pay attention to chat. As Clayden mentioned, BGs are just like dungeons; it's important to have some basic consideration for the people you're grouped with and not be a hassle.

If Trapped really wants to do some stress-free PvPing with their friends, they can try and set up some War Games with friendly guildies, or jump into Tol Barad (as long as a player sticks with the group and stays within the range of a base's flag, they can focus on simply fighting and getting kills while still contributing to the team).
