I am on US Stormreaver, horde. I am the guild master in one of the better guilds on our server. I have already been getting in contact to organize a 40 man raid of heroic raiders from our server. Talked with several other guild masters that are game for it. I expect like any hard boss, its going to take some attempts to get it down. But with good organization and bringing a select group of good players then I am sure we will kill this weekly. Honestly it seems like the intention of this is to be something hard for the more hardcore population in the game. I don't really see any problem with this at all. I mean not everything has to be super easy, and intended for everyone to be able to kill. This is obviously skill based fight strictly intended for the more hardcore guilds. I mean not the end of the world. Add PvP grief and its yet even harder. I'm looking forward to it. There's still another easy mode world boss that will be available for the masses to down weekly, probably on a 15 min spawn timer just like Sha of Anger. It's amazing some of the complaining. It's a hard boss, get better gear, get into a better guild and I'm sure you will kill it. Servers that organize this the best will be better off. I wouldn't be surprised if it doesn't have a 15 minute spawn timer too just because it is so difficult. Just my $.02
