I also remember scenarios were so unpopular they had half hour queues to find three people before they bribed people into them with excessive amounts of valor. Wow's issue is since the start it catered a large playerbase that don't seem to actually enjoy playing mmorpgs but got hooked by the social aspect of it. Now that internet has opened up more it isn't surprising wow is falling off.
These desperate attempts to cling to people who have only a passing interest in gameplay is going to do a lot more harm then good.
