This hit me right in the feels as well... I personally was too afraid of that kind of bullying when I was new to the game, so I refused to raid, and instead stuck with battlegrounds. Finally, I had a friend notice how terrible I was, and he instructed and guided me, molding me into the player I am now. I have done my best to pay it forward, doing the same for some guildies that my husband and I picked up a couple years back. They were a mage and warlock, husband and wife team, whose DPS was inconsistant and usually below the tank as well. My husband, being a warlock, helped out as best he could. I didn't know anything about mages, but the friend that taught me all I knew, did, so I grabbed him and asked him to teach our new guildie everything he could.
Point A. Helping these guildies out earned my husband and I some wonderful friends, and they always come to us with questions about mechanics or rotations, because they know we will not make them feel more inadequate than they already do. It would behoove us all to remember that we all learn differently, and sometimes it takes being shown and verbally explained before something clicks, rather than just reading a thread online about rotations or a boss encounter.
Point B. The amount of elitism, and just plain bad manners due to not being held accountable, is rampant. LFR, LFG, all those things that have been implemented to make the game more accessible has really only served to make players whine more, sit back and be carried, not have to learn mechanics, and not have to form core groups of friends or guildmates. Nobody has to be civil to each other if they don't want to, and its just sad.
I know the community here at Icy Veins is wonderful, but perhaps we should all go out of our way to show some of our guildmates and friends the article that sparked this thread, especially those ones (you know who they are) that have sounded much like those elitist bullies.
Sounds like an anti-cyber-bullying campaign, lol... I'll get off my soapbox now. =) Cheers!
