Also Meganobz should take up two transport spaces. They're way bulkier and heavier in the armour and are the ork equivalent of Terminators, both having rules in 40k that make them take up twice as much transport space as usual.

What happens if the teleporta array scatters to a position where not all the teleporting models can be deployed out of enemy ZoC? The rules should specify. The target point for a planetfalling unit automatically repositions to the nearest free space out of enemy ZoC, does the same happen with the teleporta?
