Thanks for that - that's what we ended up deciding anyway, although he didn't end up targeting the Harlies. Which, incidentally, were totally useless for the purpose I fielded them for, which was hiding the WWP Haemonculus in. We rolled for mission and deployment, did everything properly, and ended up with Dawn of War in table halves, so I could get right in his face but not quite as in his face as I wanted, and couldn't start elites on the board! Ended in a draw, which I was extremely lucky to get!
