Yes one of the tokens has 4 classes and two of the tokens have 3. However the tokens with 3 classes have a 30% drop rate and the token with 4 has a 40% drop rate. =)

Today we hotfixed the "Not In My House" achievement to only require 2 kills rather than 10. The user interface will still display that 10 kills are required but the achievement will complete once 2 kills occur.

After a client patch, the user interface will be corrected.

It's entirely likely that there will be more BoP crafted items. What there won't be is "I have to be a crafter for item X because it's the best thing ever!" items.

We will be offering free character moves from selected high population realms to a brand new realm, Fizzcrank, to assist in population dispersal. The ability to move a character on the selected source realms will become available starting on Monday, November 10 at 12:00PM PST, and is scheduled to run until Monday, November 24 at 12:00PM PST.

In the event that these realms meet our transfer goals before the scheduled end date, the transfers to that realm will be disabled. We highly recommend that if you are planning to transfer that you do so at your earliest convenience. No characters will be eligible for these free moves once the transfers have been closed.

Once the transfers open you can begin your transfer by visiting the Character Move page located here: https://www.worldofwarcraft.com/account/character-move.html

We will continue to evaluate realms and add more free character moves as we feel they are needed.
