Maybe transports would be coffins with TNT barrels as wheels (hello, I'm 4th edition).
Or shooting would be nerfed/CC would be boosted (hello, I'm 4th edition).

-Sir? Primitives are deploying their reinforcements in forest area.
-So? Shouldn't they... crash, appearing at random turns?
-They use... planned deep strike and ships that don't crash on too tall grass. In fact, ships that AVOID collisions AND auto-unload their forces.
-Not only that, retreating enemy forces... they suddenly picked up fight! Not even Orks are so fierce!
