Exactly, drones enable quantity and precision. Geran type drones can easily fly 1000nm, and that kind of range needs wide area sensing and patrols to intercept, really expensive at present.

I don't know that a loss right now would be likely, probably a stalemate which would be ruinously expensive for everyone.

Drones favor defenders by making movement costly, there is a considerable advantage to being dug in. Air dominance no longer guarantees being free from low altitude aerial threat. Long range drones require basing further away, which means A2A refuelling, or a massive innovation in drone defence (cheap missiles, autonomous drone interceptors, sensor nets).
