I don't have anything in mind for stations, and since I've never attempted to equip these ships or see them in action, I don't really know where they'd be best used. Although I imagine that since they'll be using a lot of ion equipment, it would be best not to place them together with the Ares because they also use ion weapons.
Its possible to have different formations appear in different sections of the game. Weaker formations, light cruisers and yachts, could be found relatively early in the game perhaps around the Sung area. Medium cruisers and Huntress-class a little further down the line, and finally formations with heavy cruisers later in the game.
Yachts should be independent, retreating ships.
Light Cruisers should be independent ships.
Huntress should be an independent., aggressive ship.
Medium cruisers should come in a formation with two light cruisers.
Heavy cruisers should come in a formation with two medium cruisers and four light cruisers.
All ships besides yachts and huntress should be standoff, attempting to use their ion cannons to keep enemies at bay.
