PvP - Stone Infuser?

PvP-Stone Infuser? The idea of this build is to take the "Me/E Earth Machine-gunner" (here's a link to wiki to view the build: http://gw.gamewikis.org/wiki/Me/E_Earth_Machine-gunner; and use Aura of Restoration and Stone Daggers for a continual health regen and use Infuse Health when necessary. Of course this would require the profession combination of E/Mo, and thusly taking out Fast Casting as an attribute and still giving you that one sec cast time on Stone Daggers.

Skills:
Ether Prodigy (E) - energy management
Aura of Restoration
Stone Daggers - this spammed and aura are supposed to resupply
you with health to counter infuse and ether prodigy
Infuse Health

I don't know what to fill the other four slots with, but maybe a cover enchant to save Ether prodigy or aura of restoration? Or maybe some heals or DPs enhancing kills (though this build so far seems really low on DPS lol)
Comments appreciated

The concept is weak, mainly because the health gains from Aura of Restoration are so piddling and the damage from Stone Daggers so meaningless.
Aura of Restoration at 12 Energy Storage returns 350% of the cost of the skill as health. 17.5 health per cast of Stone Daggers. Which, due to aftercast, you can cast about every second and a half, for about 11 health per second. My suggestion? Run two life siphons for equivalent health gain.
