Some ideas that crossed my mind while reading all of yours:

Defiance: Move +healing from Wrath to Defiance and buff to 20% as others have said.

Wrath: Add dmg debuff to target while in Defiance(maybe 5% with full stacks), an absorb % per stack or a Parry buff as others have said.

Foresight: Possibly add a Parry buff on top of the defense buff.

Storm's Path: Reduce cost or increase heal and move to combo off of Skull Sunder. Gives you choice to further increase enmity, heal or debuff without losing the enmity gain from SS.

Storm's Eye: Move to combo off of Skull Sunder. Gives you choice to further increase enmity, heal or debuff without losing the enmity gain from SS.

Combos:

HS > SS > BB (Enmity)
HS > SS > SE (Debuff)
HS > SS > SP (Self-heal)

This way we are always adding enmity like PLD except we get the option of what we need at the end.

Unchained: No longer removes wrath stacks. Possibly increase CD and/or reduce duration for balancing purposes or simply reduce CD.

Overpower: Rename to Whirlwind: Spinning atk with same radius as flash. Can be Cross-classed. Possibly additional effect akin to the blind on flash but for WAR only.

Steel Cyclone: Add Heal.

Inner Beast: Our Oh #### button. Increase potency. I think a minorly buffed IB should fill ~25% of your health while a full buffed one should get you to 50% (once every 2mins due to CDs).

WAR in Defiance should not out DPS a PLD. If they would then once the selfheal issues are resolved, WAR would become preferred for the additional DPS.

The simple truth is all WAR needs is more potent self healing to bridge the 8-9% healing gap that Kitru pointed out.

Move the +healing to defiance instead of wrath and increase the +healing to 20-25%.

Everything else would just be icing on the cake. For me that is.
