yes, i am still interested in making this happen

my initial thought was a hammer kd warrior but it...didnt work out great...
so i am now turning my attention to my elementalist and the spell thunderclap to make this happen
The theory behind this build is rather simple
when the enemy is knocked down they cannot attack or do squat therefor you win

so you keep the 8 enemies knocked down at all times (or so the theory goes)
the problem with thunderclap is that you lose like 7 energy every time they get knocked down
a knockdown is 2 seconds so you lose 7 energy every 2 seconds if you hit them with lightning dmg every 2 seconds so that they are eternally knocked down
e/me with channeling and also that beautiful skill glyph of ele power will help go from 7 to 5 (thx guildwiki)
so with that here is what i got so far:
thunderclap
glyph of ele power
channeling
lightning strike
lightning javelin
enervating charge
air attune
res sig
i doubt this would work like this but that is why this guild is posted on gw guru , for your help
in final conclusion i need help to gain energy eficiently (5 energy per 2 seconds)
