mf culler dual sporker in full group

im also interested to build an mf sporker for a small group. people say its been nerfed to death but is it correct that this only applies to the solo killing potential? can the build also be done as a shadow? it is thought to actually help build up wealth in dominion, so budget is somewhat limited (few exalts, no shavronnes)

true. it was roughly nerfed. BUT! we still have awesome projectile amount/speed. so i guess dual sporker is still best culler due to electric floor. nothing can cull so effectively while staying in a safe zone. i'll try to make a tree for witch with specific mf gear. making it a superior tank, group cull oriented. and if all comes to OK point, i'll make same build for shadow. we have an insane advantage here. we can go full mf. and we don't need kill speed and damage. so everything will go for survival.later today

Is there a build actually? Im pretty bad myself at building skilltrees.
