Almost every column, I talk about Welfare Epics since they are specifically designed for casuals to get their purplez on and I just assume that you all know what I'm talking about. But Dave recently sent in a question asking what they are and I realized that if I didn't write for WoW Insider, I probably wouldn't know either.
Though some people say they heard the phrase before this, the first time I heard it was at BlizzCon. Jeff Kaplan, aka Tigole, started off the Dungeons and Raids panel by saying that the panel wasn't for people with their Welfare Epics, but for people who actually earn them. Now, I think he was partially just being funny, but I also think he was speaking up for the Raiders who are upset that all of the work they put into conquering the PvE endgame content is for naught when any casual player can pick up purples that are equal to or better than gear that drops off endgame bosses.
