So true.
I try pretty hard to maintain some sort of "sportsmanlike conduct", but sometimes I can't help but think, "Ok, deeznutz wants to sell (insert lvl 15 item that takes 5 minutes to make) for (insert price only affordable buy using rtms)......IIIIIIII think I'm gonna NOT charge that".
So ya, being competitive and irresponsible are two different things imo.
