I decided to go ahead and make a fleet in STO. Planning to do RPeries with it, by making foundry missions and using the starbase assets and ship assets in the plain game.
If you're interested, let me know here or in game. I'm @jackrostof there.
Oh, the fleet is named Battle Group Sol, we are obviously Fed side. I have plans to make a Klingon side one too, at some point, for crossplay purposes.
