I respecced to just try out Survival.  I didn't contradict myself in any way.  I am back to marks.  So whatever .. In the 25 man raids fully buffed as survival I was sporting over 925+ agility and my crit chance was outrageous.  PLUS, before you start bashing, maybe you should take into the account that usually more than one hunter runs a 25 man raid.  Whats the point of having ALL marks hunters?  None.  I am a team player and if you are going to check my armory and base your opinion on that after a "month or so ago post" then I will call you an idiot as well.
I still believe marks is the superior specc to go, if you have the right gear, gems, and weapon .. and deffinetly survival if you can snatch up close too 700 agi.  unbuffed. 
I will update you guys on this though.  I respecced BM to try it out for 2's, and it owns.  MY dps sucked, cause im so used to marks, but I lived longer and the 20 seconds I am unstoppable, you can pump out a lot of bullets / arrows.  So thumbs up to BM for 2's.  Thats it though.

Meh, Bm is okay in 2's. Where it really makes its mark is raid dps though. (excluding sunwell :| I hear it is not at all pet friendly). MM can come up to par if they know what they are doing and are geared correctly, but BM also gives a superior group buff to MM. However, you do have many valid points and are probably better geared than myself (the world would implode if I could break 900 agility in my gear) so I will let it be.
