Oh you can certainly battle outlaws if you like. I don't think I said anything that would suggest otherwise, and if that seemed to be implied, it was by accident.
You'll just want to avoid conflict with the Queen's troops. A new era is coming to Roawia, and it is inevitable. Best to wait for the right time to make a counter-offensive, and no single person or even single faction is powerful enough to do it on their own.
Regular skirmishes with rouge bands of outlaws will still continue, and likely will even increase as people are forced to flee their homes in search of remote hideaways to take refuge in. Also, as I mentioned to someone via PM, just because the Queen's forces are coming, that doesn't mean that they are necessarily going to pillage and burn their way through the countryside. At the same time, if you're a noble or knight who would be valuable as a prisoner, you best do what Mark did and head for a hideout, at least for the time being...
