There is a US one also. THE US version probably will get seen sooner than the EU, due to EU GM's seem to be way more silent than the US.
The post is about 10v25 man heroic raiding and the NEEDED tuning it needs to get, hopefully in this patch incoming. If you can contribute to the thread I'm sure the OP (Tunz) will have done us a lot! There are people from well-known guilds also taking part in the discussion. Have your say but at least read a few pages before jumping blindly into it.
