All we need is minor potency buffs and have Inner Release (IR) and unchained not sharing the same timer. Honestly, just having unchained and IR off the same timer would make near perfect for my play style. It would mean that war would be tank pulling because it would allow for the most dmg from both tanks, and when ever you need to go into defiance you will not be suffering a larger DPS loss. Having war MT allows the other PLDs to use cover and intervention, DRKs to use TBN.

Sidenote, shake it off needs to be changed. There are so many directions they can take this ability but at as it stands it is pretty much useless.
