When I go as whm in dungeon my bénédiction is always on CD because it's a wonderful DPS tool.
You can go as crazy as you want in DPS and always fully heal your tank without getting out of cleric et no matter how much mana is left

And stoneskin 2 in 4man is most of the time pointless except on boss... and it depend if the boss have a wide aoe or not

@Gemina when you use dissipation as DPS booster or mana regen you have to have you're swiftcast for the fairy because it's so long to cast her
(Well if time correctly you can always fine a down time windows to slow cast her)

Mostly i great swiftcast for emergency, this isn't need to performance basic DPS/healing dance
And i'm not burning it to please à group that want to run 5second faster
