Basically a zeal/fanat pally with infinity on merc, but you're shuffling the auras around and making them weaker. :P
You're sacrificing almost 300% ed, so unless you max vengeance for a more rounded build I don't really see the point*. Max vengeance, sacrifice, zeal and conviction could be interesting since you're doing a very decent amount of phys damage, and 26 point vengeance/convic as a backup can destroy just about anything. And you open up the merc slot previously taken by infinity.
*Because you can is always a good enough reason :P
Anything with the stats you placed is going to win at PvM. Just get a weapon switch for physical immunes. Since you have conviction and bear form, you have a lot of options there. Just think of something.
I was thinking an act3 or act1 merc could work very well for complementing with elemental damage, besides a decked out act 2 merc:
Act 1 Cold arrow Ice(holy freeze) or Any arrow Harmony(vigor/elemental damage)
Act 3 Ice/Fire/Light: Whatever you want lol.
