I used to think Steel Cyclone sucked until it started critting for 500. Course this means I only use it in a situation where I'm blowing all my DPS cooldowns. Frankly I'd love to see a combo for AOE on WAR.
I can agree with a Mercy Stroke buff, it's pretty hard to land for the heal sometimes, especially in 8 man content.
However, a lot of the things people suggest would just make WAR too easy, and probably overpowered.
