"Hi everyone,
Just some info regarding the broken quests.
While it is planned to fix several quest lines which are currently bugged in order to enable all of our players to proceed with their questing, we are currently not able to give you any specific ETA for it.
Of course, as soon as the hotfix has been completed, tested and verified, we will apply it and will keep you updated.
Thanks for your patience and your understanding."
Uh, tested? As has been proven by every patch ever released, the content is never tested. Anyways, doesn't look like they'll be getting fixed any time soon. Yay broken game will stay forever broken!!
