I still think letting Heavy Swing Build Wraith and maybe lowering the recast of Unchained would probably have the biggest impact on WAR despite being relatively small changes. Why? Well allowing Wraith to build up on Butchers block cuts down the building time by about half, it allows us to use abilities like SC, Unchained, and IB with less downtime on without full stacks which means less stress on the healers, and overall increases our DPS and self healing capability by a wide margin. As for lowering Unchained's recast it just up's our chances to do some solid DPS in a fight, that's pretty self explanitory.
