Best healing class/soul for PVP/warfront healing?

[Sarpy]

I'm not sure what souls have the best AOE healing which would be brilliant for a Warfront.

Warden is very nice to heal warfronts in. Instant cast HOTs and AOE HOTs.

Other healing specs of clerics rely on casting 2/3s heals and purifier's shields usually break before the cooldown is back up.

The Chloromancer soul of the Mage calling is supposed to be the best PVP soul for healing, add to this a Dom and a Archon soul and you not only have good healing but also good mana regen which is something no Cleric soul has.

Also, Chloromancers provide some DPS while they are healing.

Yeah, but they have relatively long cast times on their nukes (which are also their main heals), and get stunned/silenced a lot. Plus when you are trying to cast your big heal/nuke (nature's touch), you have a pretty long cast time (2.5 seconds IF no one is hitting you...and they are usually hitting you), and you have a 6 second cooldown on it.

Warden is better because they can "fire and forget" heals. Once you get a hot off, it's there, doing it's job. You can even get stunlocked afterwards, and the person is still getting some kind of heal.

Also a mage's only 2 instant heals have long cooldowns, and if someone slows down your spellcasting, even if you are specced for instant, they gain like a 1 second cast time.
