As a GM, I tend to be very interested in the goings-on within my guild. For that reason, whenever I am online I try to be on a toon that is in the guild. It makes me visible so that the newer players can see that the leadership has a presence. It lets me get involved in heroics or raids that get thrown together. It keeps me available for questions and to solve problems as they arise.
For this reason, I barely play my horde character. It always feels like I am avoiding my guild when I play him. I don’t check email or IM or Facebook when I am playing WoW because my computer is older, so I don’t want that stuff running in the background slowing things down. When I am on my horde toon I am truly out-of-touch with the guild.
Now, with the RealID connection to the other officers, I know that they can get in touch with me if something pops up. I’m not really “hiding” when I play horde.
The downside is that I’m not planning to let just everyone know my RealID info. I’m restricting it to my close in-game friends. I hope that I don’t hurt too many feelings if I refuse some RealID requests.
