How about the Valiance build http://forums.ddo.com/showthread.php?t=164323 should be great for levelling and fun to play and if it can solo VOD its definetly end game viable. It has RSII & Mass Heal so your healing will be very good.
When you get to 20 if you want to change to an offensive caster specced cleric all you need to do is a +3 Lesser Reincarnate to a pure cleric and you are all set.
