There isn't any need to kite them.

As said before keep Gaurda on Obey.
Keep Shadow Flare up.
First cast Tri-Disaster when they get close enough.
Then Cast Bane, and command Guarda to use her AoE move.
They should all be dead before the tank takes any real damage from them.

With all this within in 3 seconds they should each take

Bio I - 40
Bio II - 35
Miasma - 35
ShadowFlare - 25
Tri-Disaster - 30
Gaurda AoE - 90

For a grand total of 255 Potency. The remaining dot ticks should finish them off before they get to you, considering they should now have also been bound by Tri-Disaster. You should save Enkindle for the last group just in case.
