Impossible to do as MM. Unfortunately, MM is all I've ever played and I don't feel like learning BM. Quite a dissapointment.
Did they change the adds being immune to in within the last two weeks? I completed this about two weeks ago and had no issues using FD. I followed the strat listed on wowhead. If my pet was out, it didn't work. I went SV and did the whole fight without a pet. It was pretty easy.
did this as MM spec. binding shot helps hold the adds while you burn them down with Barrage and multi shot. These 2 shots hit alot harder in this spec. Also talent spec spirit bond and glyph of liberation this coupled with Chmera shot gives you pretty adequate self heals. With this strategy it only took me 2 fail attempts. I was ilvl 523 when i did this.
