I'm pretty sure I already know the answer to this:
What is the point of Fortifications when Thunderhawks (of which the Chaos player has 8 of them) are able to enter into the majority of battles?
This isn't so much a trick question or a clarification. I guess I'm just totally confused why you would make a rule (-2 to damage) but then let something that's fairly common (thunderhawk) to constantly circumvent said rule.
It makes Rogal Dorn totally useless, at least while defending.
Yes, I suppose it's conceivable that an opponent doesn't have all their Thunderhawks out...but why would they not?
