I believe there are (at least) half a dozen 'regular' posters on LPSG who either play WoW, or used to.
I personally play Guild Wars, though my account is unused and has been for along time until I get my higher-spec PC back in action. I tried WoW on the 10 day free trial sometime last year and the things I enjoyed about it were almost balanced out by the things I'm wasn't so fond of.
What annoyed me most, however, is that blizzard sneakily tried to charge me for 6 months subscription without any authority. It was enough of a red flag by them for my credit card company to ring up to share their concerns with me and ask if it was a legitimate payment.
I guess it all sorted itself out, as no charges ever went through fully.
Assuming I had the time, I'd probably play WoW myself if there was no subscription fee involved. I'd rather play it with people I know than meeting players from the game itself, though.
