I'd say a pressing need for scenario use is some allied armour, and axis means of supply/transport. As the GV's aren't so closely modelled as the AC we can go further with substitution, but we do need two differing armour silhouettes.
I think you'll see more hurris up on the Mindano terrain, where there's more of a use for ground attack, and as the strat is further defined.
Texturing the cockpits may not be applicable, but I'd like to see a bit more deferentiation, and the correct gauges. I really don't understand the logic that asks for every last ordinance load out ever recorded, but misses the fact that all the gauges are in the wrong units.
