I've got to chime in and say thanks to Skari. It is awesome to see another player who loves the DE and understands the art of wound saturation. I love to see the anguish on a Grey Knight or Deathwing player's face. They are always so confident in their low model count armies. They never expect to be whittled away by AP 5 weapons.
As for Ravner298 ... Yeeouch!!!!
I don't know many armies that could take that kind of abuse, least of all DE. Night Shields and proper positioning is about the only hope you could have. That and turn 1 Night Fight(I always roll on the Stratagy Warlord table, hoping for a 2 with DE). Maybe their next codex will have a Night Fight trait.
Anyway, if you are going second you should be able to set up conservatively. Normally a dangerous gambit for DE. With the speed of the LS Storm it is tough but be as far away as you can and spread out. Try not to let the speeders shoot the same target(our vehicles can sometimes survive shots from 1 unit but rarely 2). Obviously a Hammer and Anvil deployment works best here. With Night Shields, you can set up 43" away and be safe from the speeders. Your opponent will scout, then move turn 1 and be just out of his reduced range but be perfect for reprisals. You might leave bait to tempt them forward.
Unfortunately, this only works if you know you are going second and only ideally on Hammer and Anvil. If you set up first and the initiative is stolen is usually how most DE defeats are born. When going first we have to set up aggressively. And that puts us right in the fire lines. Hope I was helpful and not too out of it from my hiatus from here.
