I am on a rogue assassin now, so I use EA to level with healing aura, then US to heal at cap since rogues don't have healing built in. I am also SWF so can't use boulder's might/FoTW effectively. I'm not really sure what mantle is best for you. I'm guessing dreadnaught, since you are already so invested in it for dire charge so you can get the upgrades to it easily.
