14/52/5 is the highest MM spec I could come up with on the newest spreadsheet.
I intentionally adjusted my gear to Haste Cap, and assuming there are no bugs on the latest spread sheet or in game (I'm looking at you, Armor Pen), without much work I had an estimated DPS of ~6600 in currently available gear (except the upgraded Kirin Tor Ring.) I have no idea if this is a good number for the current PTR spreadsheet, but it's way higher than any numbers I've been able to get with MM on the live sheet.
Although Arcane shot appears on recount to be a sizable amount of your DPS, the only components lower than it are Aimed and Steady Shot when you take into account the fact that Chim controls all the damage for 3 portions of your DPS and AS isn't on Piercing Shots, so the 2 points in Survival Instincts are less than impressive.
Also, RR is amazing. You can go for almost 3 mins on a Training Dummy before you burn through your Rapid Fires. It does screw with your timers, but this is completely devoid of raid buffs, so assuming JoW and other applicable buffs, MM is probably one of the least OOM-prone specs assuming they leave RR @ 95%.
I really can't see why people want to gear out of FA. Any fight with AOE damage is going to fuck with your shot rotations which will probably lose you more DPS than working gear around FA would gain you. Every other class in the game embraces hit talents, and the only reason Hunters didn't is because it was broken in regards to our pets.
