E/X earth build, needs improvement

I have been playing fire on my ele for a while, but fire is starting to get me bored, and with the new earth skills in nf, thought I'd try out some earth build, so far it has done more damage than any fire build I've run, but I feel it can be better, anyway:

Attributes:

12+1+3 Earth magic
12+1 Energy Storage

Skills:

Earth Attunement, Sandstorm, Eruption, Dragon's Stomp, Ebon Hawk, Glowstone, Stoning, Rebirth.

Start off with earth attunement and cast sandstorm, eruption, and dragon's stomp on the most clumped up group (preferably melee-ers), during the recharge ebon hawk to give weakness to enemies (usually conditions are met on the melee characters, who are most affected by it), Glowstone provides some energy, and stoning is a nice damage spell which can be used as an interrupt



Note: I started using this during the test weekend where eruption caused blindness every second, for now I'm on the assumption it will be made back like that after the final changes become announced.
