Interesting idea, but I think it suffers a bit from a split personality, and as a result all of the parts seem a bit weak. The heals might be enough to keep a party up during an expert dungeon, but it seems only half as powerful as the existing healer classes. And because of the lackluster heals there won't be much time to engage in the other aspects.

Insults as a mechanic sounds hilarious, but it seems thematically disconnected from the abilities. I was expecting something more in the vein of verbal insults. The potencies of the attacks are really lacking. I also see no combos, which makes for a boring rotation (though that's nothing new for healers). I'm not sold on the RNG-based application of insult stacks, but maybe a 50% chance isn't too bad.

The rend effects seem similarly weak. Up to 3% increased damage for the entire party, versus up to 6% from AST's Divination. And you have to choose between physical and magical damage, which is a major bummer if you have both types in the party. I don't even know how to figure out which type of damage a boss does. Insult to Injury is sort of decent, but not as powerful as the big nuke abilities of other dps classes. Also way long cooldown.

Out of the goons, the heal goon seems the only one worth using. The others just do too little to justify using up what's essentially a 60-second cooldown.

Things I would adjust:
- Buff everything to better match other classes.
- Buff the enemy attack reducing rends a lot so they're an actually viable alternative/supplement to heals.
- Drop the goons. They're just really disconnected from everything else.
- Ditch the magical/physical split from rends.
- A few more direct heals.
