It looks like you are running Wind Lord with 2 tanks. If you were to solotank it you'd do a lot more dps due vengeance being at ~250-300k+ throughout the fight. Though solotanking might get a tad tricky since the nerf to HotR nova proportion not proccing Seal of Insight anymore, atleast it did for me. Before the nerf I was pretty much topping myself with every HotR cast, but can't really do that anymore ever since the nerf. Light's Hammer should be the best option for dps on Wind Lord since it will hit all of the mobs in range, whereas Holy Prism has a target cap.

Gear looks fine, you probably could get away with changing stamina gems / enchants to haste and even dropping your stamina trinket for a
rating/proc trinket or even a fullout
dps trinket for Wind Lord further increasing your deeps.
