Dark Eldar 1500pt Casual Games

Hello my fellow denizens of Commorragh!

I am fairly new to 40k and definately new to Dark Eldar (previously been running Blood Angels) as I wanted a change from the 3+ reliable save! Anyway, I play casual games with 2 friends, they generally run either Tyranids, CSM, Tau, Necrons or Chaos Daemons (as you can see a wide variety of armies between 3 gamers...) I recently picked up a Dark Eldar Battleforce for my birthday and even more recently scored a 2500pt army off ebay for AUD$420, bargain!!! So now I am ready to come up with my first 1500pt list to run against my friends, here is what it is:

HQ - Archon, Huskblade, Soul Trap, Shadowfield - 135
Haemy - Liquifier Gun - 60

Elite - Trueborn x 3, Blaster x 3 - 81
Venom, NS, Extra Canon - 75

Trueborn x 3, Blaster x 3 - 81
Venom, NS, Extra Canon - 75

Troops - Warriors x 5, Blaster - 60
Venom, NS, SC - 75

Warriors x 5, Blaster - 60
Venom, NS, SC - 75

Wracks x 5, Liquifier Gun - 60
Raider, NS, Dissie - 70

Wyches x 8, Hek, HWG, PGL, VB - 121
Raider, NS, Dissie - 70
(Archon and Haemy catch a ride)

Heavy Support - Ravager, NS - 115
Ravager, NS - 115
Razorwing, NS, FF (Lance) 165

I think it works out to be roughly 1493 points. We are pretty casual so its not a big deal if i go over a little bit... Anyway, I guess my question is do you have any suggestions as I will probably be coming up against Tau soon and what is the tactical idea behind the list (as I am fairly new and I have read a few of the lists on here, but generally speaking get abit lost when it comes to deployment, etc.) Will also be coming up against Nids soon, so I guess drop the HWG and upgrade with what??

Thanks for the input!

Cheers!
