I used to play 40k on table top an for gods sake i recall when the necrons where released, and 1 model was released with white dwarf given to you for free (still got it some ware). along with the 36 thousand point infantry army an the 23 thousand point tank army for my imperial guard army... must crack it out sometime an play a game with a few old friends.
The new DOW i haven't had a chance to play but basically DOW is played in surges, build a army seek an destroy. hold ground do the same. I would rather see it turn based and you have limited resources like in the Table top game. a set amount of points you can spend before a battle to chose your units an maybe the chance or reinforcements at various points.
Infiltrated unit such as rattling snipers an Marine scouts ect.
