Twisting Nether had him pop up so alliance side managed to put together some raids using CRZ. He's definitely not "easy" per se but the fact that you can just keep zerging him is what makes it feel easy.
Also because I wasn't the one that put the group together for TN but how are others doing this CRZ? Is there a place to find out when oondasta is up and people are forming up groups using CRZ? I figured it might be a website or forum.
