Gonna test this out shortly as well.
I think wannabehacker brought up a lot of good points on spell lineup. A second Intervention spell over a Contravention makes more sense. It heals for more and you don't have to target the mob. Also, while stun was an improvement over just a sole nuke it's still pretty blah for the reasons mentioned.
With the new Promised heal Cleric AA launching with the new expac people will also probably want it on their bar so dropping out another less-useful spell to make more room would be good.
Something like:
Ward, Remedy, Remedy, Emblem, Word, Promised, Renewal, Intervention, Intervention, [Cure/Issuance/Contravention/something/or a second Renewal], DI, Shining/swap spot.
One of the issues I've noticed is that if the tank is close to max HP the Cleric just idles and doesn't cast any of the nuke stuff anyhow so the Contraventions aren't giving you any DPS. So, might as well have better heal nukes [Intervention] for when she's actually doing something.
While I know you said it wasn't helpful I would also say it seems like the casting has slowed down between the original releases and the past 2 or so beta releases. There have been more 'close calls' healing-wise for me even doing lesser content.
Anyhow... gonna go see how this release is
