necro-posting my own post (yes seems like a bad habit).
Since you helped with some really good tips, I want to give some feedback about the fight.
Finally we did manage to down Brutallus. After some weeks of bad raid setups which prevented progress raids against Brutallus we downed him tonight on our third day of attempts.
It all worked out a litle different than I expected a few weeks ago.
We did Brutallus with 2 hunters (me as SV and a BM hunter with cokie cutter spec).
I tried different talent builds and for our kill today I used a 5/20/36 (with efficiency since the BM hunter had the improved hunters mark skilled).
As raid support I had a feral druid and a resto shaman. The bm hunter got a enhancement shaman, rogue, ms warrior and ret pally in his group.
Since I had no mana problems at all (yay ret pally and resto shaman) I used 3 haste pots and 0 mana pots and ended the fight with 80% mana left. The next time I will skill the improved hunters mark since the BM hunter ran low on mana on our kill try (he had to use a mana pot and could only use 2 haste pots).
Scorpid sting duty + soaker group (a lot of steady-cast interrupts) + burn during the fight (~10 seconds lost dps time because you have to run to a safe spot and back to your assigned position) cost me at least 200dps so I'm feeling ok with my performance of ~1.8k dps on the kill try.
And since you all wanted webstats and logs and stuff, here are the stats of our brutallus first kill:
clicky The report is anonymous since we don't want the reports to be public. My toon is named Dione in this logs.
Thanks to you I switched to a 3:2 shot rotation (and I also got my 3.0 speed bow the last week, now I only have to be lucky to get me some haste gear to really produce more dps).
