Sin Eater Inquisitor, is it worth the loss of domain?

[Vahanian 89]

So I have an idea for PFS to make a Half-Orc Sin Eater Inquisitor of Ragathiel. Is the Sin Eater ability worth the loss of domain and a teamwork feat?

Close enough, at least on a melee or archer build. It's not the best thing ever, but free healing is solid.

It's certainly good enough not to cripple your character, so if you want to play one, do it.
