First off I'm going to admit that I began in mid-Wrath (August of 2009). I know some people are automatically going to not listen to anything I say now, but you're just validating my point.
Why is there this bias by a decent amount of veteran players (specifically those who began in Classic/BC) against anyone who began in Wrath/Cata/MoP? I seriously don't understand it. Going on to any sort of forum and saying that you began playing after BC is pretty much an invitation to be harassed and screamed at by the other people there. I've had numerous issues different times with elitist pricks who act all high and mighty JUST because they've been playing since BC or Classic.
I really don't get it.
