2K First army

As the title mentions, I'm just starting 40K and decided to go with the Dark Eldar. The guys that I'm playing with do 2,000 point battles and I wanted to draw up my army list before I purchased any minitures. I will mostly be going against an artillary heavy Tau army, a special character heavy space wolf army, and infantry heavy Grey Knights. In a couple of months though a massive Ork army will be coming also. After spending a couple of days poring over the DE codex as well as a couple of other armies' codices, I decided to go with what is no doubt a common strategy of using speed to avoid giving the enemy a chance to shoot me while I control the battle and decide who is attacking whom. With that in mind, this is the army that I came up with. Any good ideas with the logic behind them explained would be greatly appreciated.

Close Combat and Character Killer
Baron
14 Hellions
1 Helliarch + claw
Total-380

Close Combat
The Serpent-150 (deploys with Kabalites then joins Incubi)
9 Incubi+Klaivex+Demiklaives+Murderous Assault-243
Dedicated Raider+shock prow-65 (after dropping troops off into close combat, begins to hunt tanks)

5 Wyches+Shardnet and Impaler-60
Dedicated Venom+Splinter Cannon+night shield-75 (after dropping troops into close combat provides long range firepower)

Troops
10 Kabalites+splinter cannon-91 (deploys with The Serpent)
Dedicated Raider+shock prow+splinter rack+night shield-85

10 Kabalites+shredder+splinter cannon-96
Dedicated Raider+shock prow+splinter rack+night shield-85

Fast Attack
9 Reavers+2 cluster caltrops+ grab-talon+ 3 heat lance-284 (the idea is to use my reavers to destroy enemy troops while they fly over them then into cover where they can't get shot. This group also doubles as a tank hunter)

9 Reavers+ 3 cluster caltops-258

Objective holder/Tank hunter
Talos Pain Engine+chain-110 (The intent is to use him to hold the objective near me and possibly do some tank hunting if necessary)

Thank you

Okay, first wrong forum, this should be posted in the army lists section.
Second for such high point games, you have too few troop choices. You will be needing more of these as they are the only ones who can hold objectives, other choices (such as Heavy support, elites etc.) can only contest objectives (denying your opponent to claim an objective by being as close as him to it) that means that you talos can't hold objectives.

Also I don't think that Incubi are quite efficient at 9 of them in a group (take any DE strategy from me with a grain of salt, since I'm totally new to this army). I think they are hard enough to be chilling at 4 (with a character) or 5 (without) per group. But I guess it's up to personal taste as well.

Also on another note I believe you have very little anti tank in your list, you should consider using a couple of Ravagers and putting blasters in your kabalite warrior groups (instead of shredder, since they can dish out enough anti infantry with their splinter rifles anyway imo).

Hope you find this helpful and best of luck!

Reported for move.

I would try to fill every Troop slot first (Troops = good and cheap).

I also would rethink builds of Your "point eaters" - Incubi, Reavers, Hellions. They cost a lot and while they pack a lot of power... I don't know if You need that much in one unit (s).

Also, only units taken as Troop that also aren't vehicles can hold objectives. Talos can only prevent enemy from holding one (he don't "score").

Thank you for the advice so far. Also I reposted this in the correct section because I realized that I'd clicked on the wrong thing, but I can't figure out how to delete this post.

Only cartain mods (Patrons and Dark Muses) can do that. I can't (not my department) but that's not a problem, someone will do that

Modded as requested. Gobsmakked.
