I play the dark eldar. Venoms with dual splinter cannons are amazing. Corpsetheif is a must. Scalpel Squadron is a great thing for tournaments, allowing you to null-deploy. Wracks are mediocre. WWP's are great with allies, not really needed for DE unless you are using it for a grotesque unit. Blasters are beautiful. Reaver jetbikes, should only ever be upgraded with cluster caltrops, ranged weapon upgrades are a waste, since they HAVE TO jink every turn. Any thing else?
