yes this build is untested, yes there are million better builds, and yes this build is probably pointless, but i was hoping that it might appear a bit of fun for a few people
build changed due to flaw. now even more pointless
So here are the builds involved
Fast Cast Fire Ele

Snare Ele
[build prof=Me/E box fastcasting=11+1+1 watermagic=11 inspirationmagic=8][water attunement][skill]auspicious incantation[/skill][skill]deep freeze[/skill][skill]ice spikes[/skill][skill]water trident[/skill][skill]power drain[/skill][skill]sunspear rebirth signet[/skill][/build]
[build prof=Me/Mo box fastcasting=12+1+1][echo][arcane echo][vengeance][/build]
2 Monks
So, what's the (new) plan?
i'm sure another flaw will be found but here it goes. this team revoles around the fire ele dieing, i.e. they will be sacrificed.
The necro casts death nova on the fire ele. The water ele uses attunement>auspicious>deep freeze for first snare, then ice spikes when that wears off. using trident for knockdown snare (wasn't sure about elite). both the fire and earth ele run into mob. the earth ele does general tanking trying to keep the mob together whilst the fire ele fires off as many adjacent spells as possible before they die (so no healing or protecting them) triggering nova. The mesmer then uses echo and vengeance to resurrect ele and necro reapplies death nova. Fire ele runs through skills again aiming to die whilst under vengeance, thus not gaining additional death penalty. Repeat with second vengreance and arcane echoed third vengeance. SS necro is business as normal after placing nova.
the fire magic spells damage will be increased by 25% first time, 50% after death (25% intensity, 25% vengeance) on top of the additional 2 fire magic points from double dragon
[edit] bit of caluclating, if ele was to run off double dragon, flame burst, inferno and phoenix (at 25% damage increase + the +2 to fire magic after double dragon), and then die, then damage would for AL80 be (((91 x 1.25) + (113 x 1.25) + (128 x 1.25) + (105 x 1.25) x .707) + 80) = 466 in 2 seconds for all adjacent foes.
on the second run with the +25% from vengeance damage would be (((91 x 1.5) + (113 x 1.5) + (128 x 1.5) + (105 x 1.5) x .707) + 80) = 543 in 2 secs.
not sure how good that is compared to other builds, plus in reality dieing on cue isn't easy, but as i said it's a bit of fun
