I haven't really checked but is odo's fleet a permanent thing in the gamma quadrant if it is it could be the new updated version of battle group omega or whatever it was called that had a buch of ships gathered together in space with bank,exchange, and mail like a spacemall with ships that act like foodcarts/kiskos. Dominion battleship kind surround those business ships.
The asset is there so i mean i want to plop one of my captains in the gamma quadrant long term but don't want to have to call in a ship to use the bank or call in a person to use the exchange. Heck this fleet of ships could be excuse that it is to defend the gate since there is a ships in the area on of romulan gate that is defended, the delta gate is secure. the gamma gate is just a gate with nothing around it and it needs defense and it is in Dominion territory.. Alliance or not it is Dominion territory so makes sense. I know such a thing will not become a reality.
I mean the Devs have voiced ideas on things that were a good idea but later dropped because it was not worth it to do it. But i mean yeah bring back the spirit of the old battle group omega as battle group gamma.
