A little late now that you've done it but I used the wiki setup as well and had no problems with the macros provided once I realized I had to kill the whelps that were already alive around the base below the boss before I started the fight. Otherwise those macros would target those whelps which were out of range and screw me up from the get go.

I've now done it 3 times I think but I need to get back in there and start switching the toons around on the emeralds/rubies for the achievements and try the 5 ambers as well.
