I never used a white noise machine until I met my wife, who has tinnitus. Now I use one and love it. Not because I need the white noise, but because it drowns out all the annoying behavior like my dog whining for food at 5AM :D
My guild has been together since shortly after classic came out and just finished clearing 15/15 Naxx, which is quite tough with 40 people only raiding 2 nights a week.
We're all getting excited for BC Classic, but the tough part is knowing we have to cut some folks from our raid roster.
