Just a few weeks ago in the early days of April, the first Sunwell Plateau gate was opened for US realms. This gave access to the Twin Eredars boss encounter. As we prepare to close the month of April, it has been announced that the second gate has been opened as well for US realms. The opening of the second gate gives the players access to the M'uru/Entropius boss encounter. This is the first time players will be able to see M'uru again since his capture by Kael'thas when patch 2.4 came out. I miss the big guy every time I'm in Silvermoon City and don't see him there anymore. But you might know, he has his important part to do in fulfillment of of prophet Velen's prophecy.
World of Raids has some interesting information about the M'uru/Entropius encounter such as Spoilers, Possible loot information, screen shots from the PTR and even the boss' abilities. To see this information, click here.
Good luck to all guilds raiding this content. I guess the race for a world first is on again!
