Well, i have been constantly respeccing and testing new builds since the patch. I have come to the conclusion that thees are the best current builds for the following spec.
Keep in mind that all the testing was done by me and may not be totally accurate. My gear is BT / MH quality although i do not have the 4 piece T6 set.
Beast Mastery: (Average DPS: 1.3k - 2.1k)
51/10 - (Talent Calculator - World of Warcraft)
Points can be switched around from Longevity to Cobra Strikes but i wouldn't reccoment it.
49/12 - (Talent Calculator - World of Warcraft)
This is a build which doesnt take exotic pets and puts the extra points in the MM tree (GFTT) so your pet isn't focused starved
Marksmenship: (Average DPS: NA)
-Not enough research done into this spec, and i dont want to post an MM spec which is totally rubbish.
Survival: (Average DPS: 1.3K - 2K)
0/10/51 (Talent Calculator - World of Warcraft)
This is an excellent raiding build, if played well your dps can be more than or around equal to the BM hunters in the raid. This build focuses on buffing your personal dps aswell as providing good buffs for your party / raid such as the 'Hunting Party' skill.
Theese speccs are designed for DPS they have all been tested by me in various raids and on training dummies. Not all this information may be correct but these are the results i got from my tests.
P.S Sorry for my bad english.
