Look at it this way.
If factions don't want this to happen. Why is that?
I thought dominions were about story, not so different from a faction thread?
If dominions really are, not just 50 post markers for more blob. Then, you still have all that 'great character development' so why do you care if the map is reset? If dominions are working as intended, and aren't broken. Then you really shouldn't care what way the map looks.
Hard to admit it, but most of the map game isn't for writing its literally; 'my blob is bigger than yours' which isn't really relevant to what its supposed to be there for.
DEW IT.
