Congrats are in order for Ilterendi, the first guild on our server to kill Vashj. Landroval and I discussed the fight at length and it sounded very entertaining. His post regarding the kill made some interesting notes however:

"My biggest regret for the populace in general is that (So far, going by that amazingly nifty wowjutsu armory magic) so few will ever see something quite like it."
. . .
"Wowjutsu has 806921 characters in 14310 guilds listed in it's database. Those numbers represent (mostly) every player that has killed something in Karazhan on up. 56% of that 800,000 have killed High King, 42% gruul, and a spare 20% Magtheridon. SSC kills dwindle even more, with 13% of the playerbase having seen at least one thing in there. Players that have beaten Vashj drop to 2.77%, or 22,351."

If you calculate by the total subscribers in North America (2 million is the Blizzard ballpark), the percentage that have killed Vashj is just 1%. Worldwide, it would go much lower because mainland China still doesn't officially have TBC.

This is no surprise. Raiding content is designed to trickle down from the few guilds that master it quickly, giving other raiding guilds a goal to progress towards. For the rest of the population it provides mystery and perhaps jealousy. It makes the world feel bigger for all but a few, which is exactly the point. If everyone could see all of the content sooner, the feeling of having completed the game might set in for the general population.

I don't know if I agree with that, it's not bad design, but it also leaves a good deal of players feeling unsatisfied. It ~IS~ part of "The Vision", which Everquest started and Blizzard follows now in all but name.
