Alright having done Bastion and Ardenweald fully again a second time I have to give it to Ardenweald. The Winter Queen is just so much better than the Archon and while I love the Bastion NPCs, Lady Moonberry, Ysera, Ara'lon, and Shandris just win out.
I don't have much love for Bastion sadly. But Ardenweald was just something I remember falling in love with immediately. Really good zone overall can't wait to do the Campaign eventually.
