My view on TG's:
On Ozkansas, "ports" that are large airfields should get the whole package, 4x destroyers, 2x (add another one to it) crusiers, and 1x carrier
"ports" that are med/small should get 1x carrier, 2x destroyer, and 1x crusier
regular port ports, should get a battle package, consisting of 3x crusiers, and 1 or 2 destroyers. This evens out the load of the CV. Plus, if people were smart, they would "combine" the two (if they had a battle package) with a carrier so the ships with no CV could then be protected.
