From the new MOP changes:
Sanctity of Battle (Holy) now works with Melee haste rather than Spell haste.
Is this just a tooltip change? Correct me if I'm wrong, but I thought that the 3 hastes (melee, ranged, and spell) are all based upon your haste stat and they're the same #.
I'm looking at my character sheet now (unfortunately I logged off in ret spec)...I see the same haste % for all 3.
