The original brothers Zek was hard. A lot of guilds skipped it or came back to it by getting somebody to request past this for them. This raid is brothers zek, With damage auras thrown in, and the raid spread out to such a degree that its almost impossible to assist. I am sure it can and will be beaten in its current form. But it is probably the most challenging event they have had in game that I remember. I know its one of the top 3 in most difficult. If they want it to be for the top guilds only then its fine. If they hoped that all would get to enjoy the anniversary content then it will have to be tuned down. I do agree that if its going to stay this difficult it should be permanent.
