Dark Eldar - 500 pt Escalation League

The rules for this league:

The army lists at 500 pts:

1 HQ
2-3 Troops
0-1 Fast or Elite
0-0 Heavy Support

The League is to start with 500 pts then escalate by 250 pts per escalation.

So my starter list is this:

Archon + ShadowField + Haywire Grenade + Venom Blade +Combat Drugs
= 110
Wych x7 + Haywire Grenades
= 84
Raider + Disintegrator
=60
Warrior x10 + Splinter Cannon
= 100
Trueborn - x3 + Blasters x3
=81
Venom + Splinter Cannon
=65

Armies I might be fighting:
From what I understand everything but Sisters of Battle will be represented.

Suggestions for improvement are always welcomed.

Personally at this points level i think your HQ is over loaded, if you went for more venoms (i love venoms lol) you would have alot of AI and if you had more AT i doubt any army could match you. I would run with something likr this at 500 pts

HQ :
Haemi VB

Troops :
1 x 3 wracks (use them for holding an objective put them to ground in ruins with FNP they will be hard to shift)
2 x 5 wyches HWG, Venom 2 x SC

Elites :

4 x trueborn with blasters, venom 2 vx SC

that would give you alot of AT if you ended up against some one with marines to bring a couple of rhinos and a dreadnaught, not to mention guard who will always have alot of tanks.
