I've swapped Soul of the Huntmaster in for Apex. I currently have the following legendaries: Shadow Hunter's Voodoo Mask, Prydaz, Mantle of Command, Roar of 7 Lions, Qa'Pla, Sephuz, Kil'jaden's Burning Wish, and Apex.
BTW ran first 6 bosses in heroic ToS last night - noticeable improvement so far. Prepotting prolonged power is a great trick, really helps when I want a boost for a strong boss. THX!
