I've recently been experimenting with my elementalist to come up with the nastiest fire build. I have finally come up with one that allows me to hit four meteor showers in a row.
After the four meteor showers have been used, this build allows the spamming of fireball for a short period of approximatly 15 seconds until the meteor shower proccess can be performed again.
This build also has good energy management and small but effective health management which is otherwise unimportant due to the healing monk in a party.
This build has been used by myself in the Fissure of Woe in the traditional 5-man farming party.
The Build:
E/Me 12+3+1 Fire Magic, 12+1 Energy Storage
Glyph of Renewal {Elite}
Meteor Shower
Glyph of Lesser Energy
Arcane Echo
Glyph of Sacrifice
Fireball
Fire Attunement
Aura of Restoration
How the build works:
Have Aura of Restoration and Fire Attunement up at all times.
Start of with Glyph of Renewal and then hit Meteor Shower.
Use Glyph of Lesser Energy, followed by Arcane Echo and then Meteor Shower for a second time.
Then use Glyph of Renewal on the Echoed Meteor Shower.
And then Glyph of Sacrifice followed by Meteor Shower to hit the fourth.
The Sacrifice Glyph allows an Instantanious Meteor Shower, and because it is used on the Echoed Meteor Shower, the basic one does not take an additional 30 seconds to recharge.
After your four meteor showers have been used, apply the same skill order to fireball, which will continue dealing out high damage.
When the original meteor shower has recharged, continue with the original proccess.
*Some of you may be wondering that all of these meteor showers will have a large impact through exhaustion. This is partly true, but I have found that the constant breaks with enemy parties and the use of fireball, usually restores all energy inbetween meteor shower periods.
Credit: The credit goes to me on this build.

Thank you for reading and I would appreciate some feedback on what you think, and I would be happy for some of you to try this build out yourself and then give me some first-hand experience feedback.
Thank You
