The World of Warcraft Armory is my curent survival spec. I literally just replaced my helm and chest last night (got rid of my t8.5), so I don't know if this spec is still more viable than 0/15/56. I was messing around on femaledwarf and found that if I took Aimed Shot out and put 3/3 in improved stings, it would be a dps increase, but you need 15 points in MM to get improved stings. Now that my stings aren't doing 10% more damage, I'll have to run the numbers. Regardless, femaledwarf is showing me that taking out of resourcefulness or expose weakness isn't worth it for that extra improved stings point.
Scratch that last post. Since my gear change, 0/18/53 is a dps increase. Try it out, it's nice.
