Have a dark eldar force my self that I am expanding at the moment start with the core of your force for me it was 2 squads of 20 warriors with 1 archon and 1 haemonculus each with the new warp gate 40 warriors showing up where you want is fantastic for mauling troops or monsters or even impossible objectives.
From there went with 2*10 warriors in raiders
And 2*5 true born (2darklance, 2 blasters in each) in venoms
Gives you things to start with as the rest is held off board
Then 4*5 scourges armed with 4 of each of the anti armour weapons blasters/darklance/haywire/heatlance
And a nice little jet fighter
I am expanding to include 2 groups of pain engines and 2 more warrior squads in raiders to me its a solid force with enough anti tank weapons and feet on the ground for those objective points don't expect much if any of your force to last long but concentrate on the objective points total annihilation of your enemy won't work well for you unless its tanks
