Ring for Hero POST Big Bang Update

Sorry for the noob '0MGZ WH4T R1NG FOR M3!!!' question, but what ring would be best for a Hero, come POST BigBang Update.
I havent heard much about the crit rates a Hero has and any light shed on the matter would be an enormous help.

Thanks.

I'm pretty sure 10% crit ring is always the best, regardless of class. Rate>damage.
