I'm actually will be really mad if they fuck up the barrens in 5.3.
With those who have done the quests of 5.3 will will be phased away forever and wont see levelers anymore.
They did the same bad thing in westfall, i can't see levelers no more.
No way to help out friends questing or anything, really horrible phasing ever, and i'm mad they destroyed westfall for me.
