I have yet to find an EU 25man guild that got more than 1 token on Garrosh.
I've checked a lot of US 25man guilds and it looks like many (all?) of them are getting 3 tokens, one of each type.
While it's maybe random, when absolutely all your data points toward something, you're asking yourself some question. I'm not drawing conclusions yet but you can see where I'm going with it.
I'm wondering if there is a bug and would like some hindsight from the community. If you are a 25 man guild, please consider posting the area you play in as well as the number and type of tokens you got. Thank you.
