Before endgame I don't see healers making use of the 15% healing gains over Inner Beasts, as for Berserk, this should be used near constantly, pacified means nothing, you still have flash, provoke, and mercy stroke, it's a huge DPS gain, and if you somehow lose aggro after Berserking enmity combos, you're a bad undergeared tank, lol.
WARs are given offensive cooldowns for a reason, use them consistently, Unchained and Berserk can mean the difference between Phase 4 wiping on Titan or not.

I think, Storm's Path should have an overheal ability like Thrill of Battle, to a max of 1500 or so.

Make it so Holmgang, if it's resisted, we're not stuck in place - but also, all damage is converted to HP for it's duration of 6 seconds.

Inner Beast should do more healing the lower your HP, say 500% at 10% HP.

Bloodbath raised to 75% (from a trait, make it 40% base).

Steel Cyclone should have a debuff, such as silence or slow.
I think these fixes can make WAR as viable as a PLD
