Imagine if CDPR created an RTS game set in Witcher universe. Picture all of the factions, special units, heroes...whole map... OMG
Campaign to defend Northern kingdoms from Nilfgard... or the other way....playing as Nilfgard wiping out faction after faction.....having random monster encounters on the map....
Cmon people, what else would you like in it?

That would be really great and I would like it, but sadly the anonymous masses of gamers don't buy real time strategy games anymore.
