Hey, Welcome to the forum Alex =]
Your Haemonculus can't fit on the Raider with the Wych squad, since the squad size is over the transport capacity. Also, without a vechicle your Warriors will need to hug cover like a baby wants their mother or will have major problems surviving return fire since as Dark Eldar, we are squashy.
What I'd do:-
* Drop 3 Wyches from the squad, exchanging the Flail for a Shardnet (If you see a Dreadnaught you'll love this change)
* For the price of your 10 Kabalites, you could have 5 Warriors with Blaster + Raider with Flicker field / Nightsheid giving them mobility and protection while still keeping the Dark Lance
* If you want to keep the Reavers I would exchange the Grav Talons for a Heat Lance, since they are better at shooting then assault, while they still have their overhead attacks naturally. Also if you take this route I would say put 1 Wych back into the squad, then with the 20 points remaining add the Flickerfield to the Wych Raider, and then to your taste either Shock Prow on the Kabalite Raider and Venom Blade to your Haemonculus or take the other Raider and give it the Nightshield or Flickerfield.
* However, by dropping the Reavers + the 36 points from the Wyches and losing the Shock Prow (or putting your Warriors in a Venom) you could get the Ravager with Flickerfield / Nightshield (or putting a Flickerfield on the Wych Raider), which others will tell you is our heavy hitter and always loved as a very deadly weapon.
Hope this helps and hope to see you around the forum.
