After doing some thought on frost traps proccing LnL I figured I would try and fiddle with some specs myself to see what I could come up with. I have used a number of different survival based builds recently to try and determine the best one. I've tried 6/14/51, 1/18/52 and so on. After looking at it today I figure I can up my personal best DPS by a fair amount with the upcoming changes to Sniper Training by using this build:
Talent Calculator - World of Warcraft
Not sure if my choice of talents is 100% sound yet but I believe it may work well to trap dance with the new Sniper training, should trap dancing not be nerfed or changed.
I like your spec but there is a few things that I might change. As Thayer said, you do have enough haste to only need 1 point in iAotH, Personally I would put one of those points in Focused aim, take out that 16 hit rating gem as you'll still be at the hit cap, put in a little more agi and finish off your expose weakness. With the amount of agility you have, plus getting a few more by swapping out that gem, the bonus your going to get off that critt is going to be insane. Even at 1425 your getting 25% of that stacking on top, which would put you at 1781 agility. Which will also give you a greater dps overall. Going from a 66% chance to a 100% chance.
