I had something similar happen last night. Joined a group all between 317-320. I was on my 319 warlock. They literally could not get past a quarter through totems without multiple screw ups and deaths. I saw people with the aura leave, thinking they had the power. I saw people [i]get lost[/i] going between mid and their totem. After a wipe I even noticed someone with zero kills. After about the tenth wipe, someone suggested cheese. The group was all for it , "Yeah, let's get this done!" I replied, "This is the easiest part of the raid, we are all over 315 light, there is no legitimate reason why we should cheese this, much less be having any trouble whatsoever." Two quick wipes later I left. I'm sure they all thought I was an a-hole, but dayum..... that was hopeless.
