Retribution got Khador'd

Last night, I used Retribution for the first time. You can find a full battle report here :http://karchevtheterrible.blogspot.com/2009/09/retribution-vs-khador-35pts-mk2.html?showComment=1254007492716#c1342217116688210464

But, in short, I got wasted ><. 35 point army, Fielding:

Adeptis Rahn

Hydra x2

House Shyeel Battle Mages

Houseguard Rifleman (max) +UA

House Shyeel Magister

Mage Hunter Assassin

Ghost Sniper

In Retrospect, I should've used Arcanists over the bottom two, so the tier bonuses would kick in, but they didn't seem important at the time.
