Fortunately, this only affects a small number of guilds, so we are able to correct the error. We'll be reaching out to all guilds who only received one token from a successful Garrosh kill this week and providing the Guildmaster with an extra two tokens at random, which can then be distributed to any raid members who were present at the time of the kill.
We sincerely apologize for any inconvenience or frustration that this has caused. Thanks for your understanding, and good luck in Heroic difficulty!
While there seems to have been an initial error, it certainly sounds like Blizzard has taken swift and decisive action to correct the wrongs of their error. So, it is likely that the hotfix will go live in the EU with their later reset, in time for Wednesday, and that EU guilds will be compensated accordingly. Tier items are a really important component of world first races, as even a tiny gear advantage can make a huge difference. If you were in a 25-N raid and too few tokens dropped, speak to your GM!
