Blizz you have yet again done wrong. You are nerfing abilities that arent OP at all (Bone shield and Icebound fortitude) and not even trying to give us a bonus to it so i have proposed one for you.
IBF will now break us out of stuns.
Bone shield should either offer nore +dmg while active or give us a new cool ability to use the charges such as
Sacrifice Bone (yea i know cheesy name)
Takes a bone and hurls it at your opponent or ally to either inflict 246-315 damage or Absorb damage of next attack
This will use up one charge and scale with AP, could also add to cause a medium amount of threat for tanking when not enough RP for DC.
