you can ask me why i choose each an every one, and if you have a way to improve it please post here, i would also like everyone to post here to make sure they've seen this. (hunters that is
BM --this is the pure DPS raid spec.

if you feel like you are dieing to much, or running low on health.. you can take the talents off Improved revive pet and put them in endurence training or in animal bond and mend pet (if your pet is dieing)
MM --

i saved 2 talents here (instead of spending them on huminoid slaying and monster slaying) and put them in endurance training but i still get 3% damage increase cause i put them on focused fire.. but you need to keep your pet alive throught the fight to get the 3%, if you feel you have enough health you can take the points out of endurance training and slam them into stings.
SV --

right you shouldn't go SV unless you have around 550 - 600 agi on you before switching to SV. you are better of as an MM hunter if you dont have that kind of stats.
side note "*"
*for Improved hunters mark.
the only ones who can do this are SV hunters or BM hunters (with duel wield)
you can dump efficiency and put them there instead cause during raids you can slam mana oils on each weapon and never go OOM. MM hunters forget about IHM cause you are just not mana efficient (what ever you do).
