I have tried this instance 5 times now and the SECOND boss keeps blocking me... my paladin is 78 now and shaman 76. Everytime I go in the 2nd boss bugs out and will not stop the adds coming in (or hell he doesnt even come up top!) I gave up on this POS instance. I tried fighting my way to him one time and got overwhelmed by like 20 adds. Good thing there is nothing of consequence in this instance.
