To add to other people's lamentations: It's been a while since I did anything resembling RP in WoW. Nowadays, I just get on to troll people in my guild, basically. But I still know people who RP! And they tell me it's awful.
Or, rather, it's excellent if you can find the right guild. There are apparently a few good ones. And a lot of really bad ones. Alliance side is apparently overflowing with people who love A Song of Ice and Fire way too much, and play politics and intrigue in Stormwind.
*sigh.* I miss my old raiding / RP community.
