Heh, I don't think the problem will be finding enough engys. Engy's can be used almost down to level 50. They just have to be able to cast Beacon Warp. The problem will be finding enough 160+ Soldiers who want to get shot at for hours on end.
4 Crats, 2 with 7% Crit speech running, 2 with +100 Add all off speech running.
Maybe as many as 4 agents spamming the repressor in sync with each other. The repressor really is not a -Agg item. Most of the time it functions as an item that makes the mob attack whoever has done the most damage to it.
1 Trader/team. Keeping a +100 or higher team wrangle running.
The Crats and Traders are there to make the Soldiers have a high attack rating so they hit harder and more often. Might want to replace the 2 Crats with 7% crit speech running with MA's casting MoP on the soldiers when they need it and have been pulled back from the front line. Too many little programs refeshing themselves often could keep the Soldier from casting TMS when the soldier needs it.
Its the little things you can't know until you've tried it.
