Dark Eldar Webway Portal Caddies

Hey there, so myself and two friends are staying over at one's place and plan to get in a couple games over the weekend.

This is the first time I've decided to ally in some Craftworld Eldar with my Dark Eldar, primarily using the webway portal, and to get an Autarch so my Dark Artisan comes on the table before turn 4 -_- (3 games in a row that it has only come on in turn 4, and two out of those three games I even had Labyrinthine Cunning) Anyway. I started out making a 1850 list which I was fairly happy with, but I reckon we will stick to playing 1500 pt games, cheap 'n cheerful.

So I brought the list down to 1726, I could use some help getting it down to 1500 and some general advice on it too would be awesome

HQ:

Archon - Blaster, Shadowfield, Webway Portal - 150

(A) Autarch - Banshee Mask, Fusion Gun, Shard of Anaris - 125

TROOPS:

5 Kabalite Warriors - 40
/Venom - Dual Cannons - 65

5 Kabalite Warriors - 40
/Venom - Dual Cannons - 65

5 Kabalite Warriors - 40
/Venom - Dual Cannons - 65

(A) 5 Dire Avengers - 65
/Wave Serpent - Scatter Lasers, Shuriken Cannon - 130

ELITES:

(A) 5 Wraithguard - 160

FAST ATTACK:

6 Reavers - 2x Cluster Caltrops - 126

HEAVY SUPPORT:

Ravager - 3x Dark Lance - 125
Ravager - 3x Dark Lance - 125

FORMATION:

Haemonculus(Warlord) - Nightmare Doll, Webway Portal - 140
Talos - Ichor Injector - 130
Cronos - Spirit Probe 125

TOTAL: 1726

So, the most immediate changes I could make if I wanted to keep some of the more expensive upgrades on the HQs, would be to drop a Ravager and a single Kabalite/Venom unit.

The other changes I could make would be to start removing upgrades like Nightmare Doll and the Shard of Anaris from the HQs. I wouldn't really want to do that to be honest, but it may be the better option.

The nightmare doll is to make my warlord far more difficult to kill (though, he is already pretty much the toughest model to kill in this list, even without the doll)

Then the shard of anaris was to give the wraith unit a bit of combat potential as they will be deepstriking within assault range. (the banshee mask adds to that too, allowing the wraithguard to hit with their fists before the enemy goes : P)

The archon's job in the wraith unit is to just bring them down, and tank for them with majority T6 and his 2++, and then throw out some BS7 lance shots.

I could lose a single ravager and then the nightmare doll and maybe some of the other HQ upgrades, to be able to keep that 3rd Kabalite/Venom unit maybe.

Anyway, what do you guys think?

thanks in advance!

PS - The armies I'm facing are IG and Necrons (he'll be trying out the new necrons for the first time, I've had a read through the codex, but not very indepth - other than that I've just read the review of it on frontline gaming)
