You do realise the same arguement as for why the IMG needs a BC can be used against them, most IMG operations take place in rock fields, it's logical to assume that the majority of engagements IMG caps get in are in rock fields, so why not jsut have a standard cruiser, maybe even a heavier one like the RMC. Also by this same logic, since the CR fight in Magellan, the portion of Coronado not in the Barrier Cloud, and potentially Leeds, why shouldn't they have a BC?
