Help with my build

This is what my ele looks like at the moment:

Rago's Flame Staff
Pyromancer Armor from Citadel
Fire Magic: 15
Energy Storage: 13
Inspiration Magic: 3

Fireball
Meteor
Rodgorts Invocation
Meteor Shower
Glyph of Renewal (This and arcane echo allows me to use spells such as meteor shower 3 times in a row)
Fire Attunement
Arcane Echo
Power Drain (Handy for interrupting a priest that is rezzing or whatever)

What should i change on this? Any tips? Btw, i regularly farm in Sorrow's Furnace.

I think that this is very close to the same build that everyone is using right now, so it looks good. I choose to leave the glyph of renewal at home and take the glyph of energy. I do this for two reasons, two MS are ample with most mobs especially with mark of Rodgart for particullarly stubborn ones. Reason two resides in the energy managment dept., the glyph of energy removes exhaustion. Yes, I know what your saying.....but I can get another MS with Glyph of Renewal....yes you can, but Glyph of energy recharges quickly and then you can get another MS off before the initial echoed MS is over. This is just my opinion, I have several trips through SF, FOW, and I solo farm the desert with my Ele quite alot, it works. The renewal also works, but again, this is just an alternate way which differs slightly from everyone elses equations. I hope you find as much success as I have with it.
