Raiding does not mean Skilled
(Related post: Max level does not mean Skilled.)
There’s a class of player who feels that their status in the raiding game means that they’re Right. They label other people noobs, and the silly thing is that people believe them. “I have this awesome item, you don’t, therefore I know what I’m talking about and you don’t.” This frustrates me a great deal.
My guild recently brought in a new recruit. Her main is a holy priest, just like me! I’ll call her Mary. She was very personable, online a lot. She had raided a lot in the original WoW, all the way through AQ40, which I’ve never seen. She had taken over a year off from the game, and in her return was looking for a more relaxed playtime requirement while still playing at a high level. A perfect fit!
