1500 points Off the top of my head, what should an all out assault list look like to me? I would go for a nice uncompetitive but fun list. In brief (roughly):
Archon w/shadowfield, armour of misery, huskblade animus vitae
4x Incubi with klaivex
Venom with cannon
(3x) 10x Wyches w/hekatrix, agoniser
Raider w/nightshields, shock prow dark lance
6x Reavers , 2 heatlance, 2 cluster caltrops
6x Reavera, 2 heatlance, 2 caltrops
Everything will be on the board. Trying to keep out of LoS if it can. Screw objectives,a dark eldar assault is about bloodshed. So get straight into their face all down one flank. Overwhelm and conquor. Turbo everything to a flank get the reavers into their face/backfield early. Taloi protect one side of the flank closest to the middle to draw fire. Get shot at turn 1 by the half of their army that might be in range. Everything drops out and gets into anything squishy. Taloi move up, try and take out transports/anything tough. Animus vitae gets a kill, archon and incubi get stuck into the most expensive unit they can. Wyches get into everything else, maybe even vehicles with 10 av back to hit with plasma. Reavers heatlance transports or get stuck into combat. Etc etc. Operation bloodbath.
Hopefully your opponent will lose his head (metaphorically) and rush to engage this army on the flank. Abandoning objectives to save his army amidst the chaos. Fortunately the raiders are positioned to obscure as much as they can. They will rush to the aid and hopefully take the bait to forget about all tactics. (Chaos and confusion). Victory by cutting them down in combat. Shock prow remaining vehicles. Then run and hide if they bought a mech army. Ignore flyers, they cant shoot into combat and you should be on their line anyway.
Competitive? Nope. Fluffy and fun? Yes. Its what an assault list would be for me. It won't work well except in the best possible situation. Its what it should be. Not what I would do given time. Also, everything will get into assault! No compromise!
TL:DR 2/10 would not tactic again
