For some situations or IA verses I swap out Swarming Scion for Pestilent Colossus, Bloody Smash for Wrecking Blow, or Chilling Trample (with hunter's snare and major heroism) or Bloody Torch (with lingering torment and minor heroism) or Wield Soul, and Chilling Contingency for Chilling Burst (with lingering torment and intellect and endurance).
The slippery cp is good for the Molag Kena fight.
