I know you said "don't get stuck on rooftop camping" and I agree, but I'm posting this here as it's going to get missed in a different baby thread down below.
Article including Rooftop camping -

http://www.wowwiki.com/Timeline_%28World_of_Warcraft%29Eyonix's post declaring the change in Blizzard's change of rules policy for rooftop camping (and ANY form of geometry exploiting that was similar: How 'bout dem Silithus posts / buildings?) was made in October of 2006. This was after patch 1.12.0, but before Burning Crusade by a few months.
So the staff can say whatever they like on the subject, but once the server's caught up to 1.12.0 players should expect to be crushed if they exploit it.
