Uhm..
Have you considered the Spear for MH?
As you know in the previous patch the Hammer was perfect, more or less 1 skill for second for maximize DPS, now rubies Devout Servant are nerfed, cooldown increase, mana too ect...
I really dont know is there's a bug in fanaticism effect, I'm anyway totally agree about their nerf..
I can say IMHO: Melee Healer is nice and perfect for farming, leveling, PVE party (maybe..).
For PVP is you want to do DPS role, it's always better play as a caster...more range, control, tanky, survive, no need an engage like MH needs, you are always ready to fight everyone.
Let's keep update with every try you do with yours healers
