that said, heres the build:
E/Mo x 7
each one brings:
obsidian flesh {E}
healing breeze
prot spirit
obsidian flame
crystal wave
gale
ward against foes
resig
R/Mo x 1
mark of protection {E}
edge of extinction
stormchaser/dodge
vital blessing
light of dwayna
distracting shot
savage shot
resig
each elementalist brings 5 superior runes so that each has 105 hp.
for a map like underworld (which is as far as this is gonna get anyway, so ill just explain this one), the ranger immediately runs as far back as possible. the elementalists run in, put on obsidian flesh. then they start spamming crystal wave/obs flame/healing breeze until they only have about 5 seconds left in obsidian flesh. at that time they all put up ward against foes, the ranger runs in and puts up EoE.
as soon as the obs flesh runs out, everyone should die relatively fast to seriously anything (they have 105 hp, right?). the ranger puts up mark of prot on himself and it should theoretically be gg.
weaknesses in the build:
-chillblains = gg (if they use it the ranger should run in asap.. but its hard)
-no death nova (this one sucks if you arent doing enough with crystal wave etc)
-no sacrifice meaning everyones gonna die at random intervals (which isnt too good if theres a heal party spammer)
theres a better one thats really similar to this, but im keeping that one to myself until i try it

try not to blame me when you die miserably
