As previously announced (http://us.battle.net/wow/en/forum/topic/1567814533?page=1
), Conquest items requiring 2200 rating were made available today, January 25, with the exception of weapons. We plan to make the 2200 weapons available approximately two weeks after the release of patch 4.0.6.
The decision to further delay availability of weapons requiring 2200 rating was not made lightly. Currently very few guilds are clearing PvE content that drops weapons of this caliber, which would make rated Battlegrounds and Arenas the primary source for top-tier weapons. We of course don’t want players who are pursuing PvE content to feel as though they must engage in heavy PvP to obtain these weapons in order to be competitive or successful.
We do have some plans to help avoid similar situations in the future, and we’ll share more details when they become available.
