That was part of my point though - people are saying "virtually nobody ever raided"..... doesn't ring true from everything I've seen and I've played since launch, does that mean everyone is raiding all of the time? No, but saying 1 to 5% does sound like a silly number, who at some point hasn't tried raiding, besides people that don't hit max level and pvp'ers?
To be fair, I've seen real casual players go to the forums for all sorts of stuff, like collecting pets, rare spawns, or just to talk about weird stuff in the general forums.
