Last Stand of the Zandalari

For those who want to know when the release dates are for the different difficulties/LFR wings:

"With the release of Patch 5.2: The Thunder King, the vast Throne of Thunder raid will become available. As in previous raid tiers, Raid Finder wings and availability difficulties will be staggered.

To access the new Raid Finder wings you will need a minimum average item level (ilevel) of 480.

This is our current schedule based on a planned patch release date of March 5. If the patch is delayed, or if we determine any change is needed, we’ll update this article.

March 5-Normal Throne of Thunder
March 12-Heroic Throne of Thunder and LFR Wing 1 “Last Stand of the Zandalari”
March 19-LFR Wing 2 “Forgotten Depths”
April 2-LFR Wing 3 “Halls of Flesh-Shaping”
April 16-LFR Wing 4 “Pinnacle of Storms”"

Your calendar is too low level. You need to get two or three more levels. Luckily for you, your calendar levels on it's own roughly at rate of 1 level / day

What themeii was trying to say is that you cannot queue for the LFR yet, until tuesday (today), it was not released yet at the time of your comment
