You never had to spec BM. If you were an engineer or you had noggenfoggers it was dooable. You clear all the trash in his room and that whole really long corridor before his room. Kill the random guy right before raptor boss and feign death. Get your slowfall then mount up, face aggro them, raptor is way faster than the boss, slowfall down the corridor while unloading on raptor, feign to get your pet aggro back and finish raptor off. Then just run around disengaging the boss, will take a little while, but its the same basic concept I use on my mage to solo him :P
