Which Scout class to pick?Follow

A friend and I are going to start an Assassin/Healer team and he is going to be the Assassin. I was wondering which Priest Sub-class from Freeport would be best for this combo, I would like to get the best melee damage class that heals because, well what can I say, I love to hurt stuff. I realise no Priest class will do great damage but just wanted some opinions on which would deal the most damage for what is available. Any help would be appreciated, thanks.
