I was questing in Silverpine Forest and got a bit stuck there. Where can I start new lines of quest? The Board (in capitals which usually recommend you new questlines) doesn‘t have any quests.
What can I do?

I downloaded the ptr launcher and can‘t find CoA in there. Yes I know, it will be officially released in 2 days. But I‘m unpatient as hell

Everytime I try to download it says download failed, please check internet connection.
Internet runs perfect tho.
I‘m based in Germany, and tips?

I saw Acension‘s Videos on YouTube about the 21 class system and man that sounds so great! 21 new classes which all fit the WoW feeling so well. So here are my questions:
- Can I already play or is it not released yet?
- Is it / will it be free?
- Have you guys any experience? Is it fun?

I recently did my first Raid as a tank ever, and man these boss mechanics a really overwhelming as a Tank-newbie. I play Blood DK and love the spec, especially in Solo content. I watched a video about the boss mechanics in Midnight and must say that raiding as a Tank is absolutely not easy for "new" players, even in LFR.
Is this just me?
What are your experiences?
