I saw this on the Dark Eldar Facebook group. I don't know how true it is but thought I'd share it. Courtesy of Maciej Machowicz.
Everything was written from the memory so mistakes could been made
I've just read our index. I've got few observations to share.
tl;dl it seems really balanced with every unit viable but without any really big power boost.
-First of all we have to wait for the proper Codex, becouse it's just the basics. Minimum special rules for the units and without any special items except weapons.
-Forget what you know about points values. almost everything have a different cost maybe except Venoms.
-Vehicles with 10+ wounds and being less likely to blow up should really benefit our faction.
-FNP is like in 7th game turn based.
1: 6+ inv
3:+1to hit but CC only
4:immune to battleshock
5: -1LD bubble for the opponent
-Combat drugs are about the same, but with +2 mov and +2 LD
-Poison - no suprises there, 4+/6+ against vehicles.
-Coven units have 5++
-Basic movement value for our infantry, including covenites seems to be 7'' Riders are faster than Venoms.
-Archon would be a cheap HQ filler. Even Bestmaster is more expensive O_o and new huskblade is a joke. His special boost is just use my LD or whatever.
-Haemonculus give +1t bubble but only for coven units.
-Succub seems about the same, I forget what she gives cult units, rerolls maybe. Archite Glaive is now +2s but -1 to hit
-Court are similiar I think to what we had in 7th.
-Warriors are 7 points.
-wyches are similiar but with 'no escape' rule.
-Incubi got reasonable price and the mandrakes seems really good
With nice shooting attack, 5++ and Deep strike.
-beasts are looking interesting, high attack values and movement. Beastmaster let them use his LD and give to hit rerolls.
-Reavers are about twice as costly O_o Got second wound but losses all interesting abilities. Caltrops now activates only when the opponent is running away. Meh! Their turboboost is just straight 24'' now.
-Scourges are cheap and have that no scatter Deep Strike.
Haywire now damages vehicles on 4+ and deal 1 bonus mortal wound or D3 if you roll 6 to wound.
-Wracks and grots are about the same as they were. I was hoping on some more wounds for the G-Unit
Haemoculus seems mandatory for the +1t now.
-Rider cost about two 7th ed Riders O_o you can mix passengers now (except Incubi) All have 5++.
-Ravager is now the same price as a Rider.
-Venoms should be gold. -1 to hit for the opponent and still you got this 5++. Obvoius upgrade for the splinter cannon is now free I think
-Flyers with more wounds seems really good now, But they are just -1 to hit for ground units. Minimum movement is 20'' now. Maximum depends on wounds left.
The Bomb is generating D6s for every model Voidraven will fly over (3d6 for monsters/vehicles) maximum is 10 dice. Then they will deal mortal wounds on 4+
-Taloi are cheaper but nerfed with only 6t/6s
got 8'' movement but now could explode. The blast deals mortal wounds so can easly damage other taloi. Of course they got more wounds now.
-Cronos is more expensive than Talos and give no buffs I think. He is the damage dealer now.
