Possible, or is it still US only?
I would assume the postponed maintenance on Thursday will enable it for EU as well.
Blues say its tomorrow, shame as I was keen to use it tonight for my raid group, ah well.
It's not working on EU yet. This thread can be closed. Just tried it.
It is working on EU, am currently in SoO 10H, after entering the instance on 10N. My character is on a German language server and in the same raid instance as somebody on an English language server.
