THanks for the clarifications Chroma

These limitations make sense and you are right, if one tries to attack the transport it has to be devastating because of the reasons you give. What I meant was, if they would flee in the escape direction in turn one, they would possibly be broken in reach of an ork formation that could potentially wipe them out by an assault. That was my thinking. Such considerations is what make such scenarios fun

I liked the escort duty scenario in BFG also for this reasons.
