kay the more I think about it the more I think DA are underestimated- they outperform guardians nicely for the same cost...
1 farseer with jetbike, singing spear and guide- 128pts
1 court of young king 1 avatar, 5 DA exarchs all with them Direswords and defend/distract - 330 points
Troops
9 DA w/Exarch w/defend w/distractw/power weapon in WS - 274pts
9 DA w/Exarch w/power weapon - 144pts
10 DA - 120pts
10 DA - 120 w/Exarch w/power weapon
Elite
10 guardians w/starcannon and warlock w/conceal AND a starcannon - 166
heavy support
1 falcon w/scatterlaser w/spiritstone w/holofield - 180
total- 1486
the tactics: kill the avatar and have the DA Exarchs jump in the falcon, which the seer is following guiding, if the seer gets near enemy lines he kills tanks, the DA serpent zooms up WITH the falcon, and they drop their charge off together, while everyone else advances slowly dying but hopefully getting their Exarchs to combat after wrecking havoc with shuricats...
math: 1 units avengers with Exarch firing on average marines: 15 hits (the average stays the same) 7 wounds, 2.some dead. the problem is getting them there. alot will die on the way... which I'm worried about.. but the Exarchs will hopefully wreck havoc and the fore runners (WS with DA) will put them off for a moment...
