We may want to practice our Exterminatus technique here, but I don't think it's honestly practical. The enemy has a vast amount of firepower to put to the task of shooting down any rocks we throw. Let's see what our resources and options are. We have the other planets of the system with however many Orks are on them. Our options with them are to set up a daisychain of starships or Roks to tellyport them to the planetary battlefield, or, if we're too short on ships to assign to that, we order them to start killing each other in place to build up extra WAAAAAGH! energy. We have 11,000 units of WAAAGH! energy. 3,200 Units was sufficient to pin a Tombship in place so it could be Rok'ed, but I think there is sufficient enemy firepower to disrupt a Rok being used as a projectile, and we're short one Hulk for traktor beaming. It sounds like a very risky proposition to me. An alternative suggestion I have at this time is to fire a bendy-beam Psylance, and vaporize all of the Necron Escorts and other light ships in one quadrant of the enemy fleet, so we can punch through to deliver the Primork and his boyz to the planet below. From there, we can begin boarding actions on the heavier ships using Ironklads, they're a new twist on things that the Necrons haven't met yet. We know they can defeat Tellyporta attacks, potentially. Tombships can either fight off boarding parties, or else they can phase out when boarded. Either way, they're neutralized for the here-and-now. It's a little too late to suggest the Zsinj Doctrine - Never Fight A Battle On The Enemy's Terms. Else I would've thought about it and offered that we just flip Traveler the bird and go travel on over to his employers' home tomb worlds to make him dance to OUR tune. Sorry.
