Veil and Shake are better than Heart of light and Dark Missionary. Because most cases any physical raidwide damage the healer group mitigation will be higher at 10% which will take base. So the 5% will most likely be 2.5% or lower depending on the group combined mitigation. For magical aoes which are most of the raidwides are great.

Like others have said. I think they will scrap all of the tank group mits and turn it into a role action and make it available at low levels. Thats homogenization but I think they need to homogenize some things to allow for them to add more unique things to jobs.
