I've actively tried to get some normal raid groups to do it, but we always miss a teleport (especially when he doubles up and we don't see the second) I figure it's a matter of time before it's found out for certain. Killing him legit is faster and more enjoyable. The shield guy actually gets to run around and beat on stuff to his hearts content. And it isn't nearly as hard as people make it sound. If you're group happens to be a higher level and nobody's done it the normal way. I highly recommend it. If you're the regular level I still recommend it. But I understand how it is convincing groups to do it this way. Most want it quick and painless and being lower levels doesn't help your argument when pitching the idea.
