We've been keeping tabs on various WAR bloggers who have shared their thoughts. Keen feels that the zone flips a bit too easily but is happy with the new content overall. LotD isn't the mecca of RvR that Bootae had hoped for, but he's still quite pleased with the quality of it (over the quantity). As for Thulf, well he was actually drawn back to WAR after a couple months' absence to give it a shot. It's too early for him to tell whether or not he'll keep his subscription open for it.
This writer is still waiting for the dust to settle. I don't know if there are any major issues with the zone or its effect on RvR, but I'm hesitant to jump in head first and have my experience spoiled by anything. The ancient undead can wait a little longer for this explorer.
