Aren't they just dailies that you do back in the instances? Or am I missing something ? True, there is a gate with a portal on it I can't access, but I thought it was only decoration that accidentally ended up with a portal or a portal to - as of yet inaccessible - raid ?
This is just quest hub like Ox-clan Merchant Camp in Nan Curunír for Isengard instances
All quests what you seen here can be completed inside Carn Dum Instances. Yes, Carn Dum have more places (showed up in recent stream with Scenario), but they closed right now because you don't need them in this update. Even when raid was available on BR, you don't need any gates/portal to enter
