I play WH40k, though I always lose against others because they rush through the tech tree to get tanks (which is called the tank rush, and the tanks are about 5 or so in numbers), and it's annoying even more in Quickstart. I even lost against people who play Imperial Guard and keep all their Guardsmen squads together while the team I'm on doesn't bother sending me any aid.
I prefer to go slowly up the tech tree, and it seems I have the dumb luck of getting the lousy teammates.
Well, so long as no one tank rushes really early, I'm alright playing along with you. I prefer muscle-bound infantry all the way, and I'm able to mass a big number of troops by the end of a game (maybe I should try mass Tankbustas sometime?). At least they brought back the heavy weapons on the Chaos Raptors.
I'm also looking forward to Dark Crusade as well, mostly cause of the Necrons' mighty Wraiths and such, even though it's slow on foot (I do pray they include Necron Destroyers and Heavy Destroyers).
