The rule was a worthy experiment and would be a good idea were the player population twice what it is. I don't have a pony in the race and you could make a case that the damage this rule does is worth the benefit it brings .. rather than plugging your ears and insisting that it doesn't cause any harm.
Dwilight is still the place I have the most fun playing, by far. I don't know how much the one-player rule is a cause of that. It's certainly not the only cause, and it could very well be that it is in fact a minor aspect. However I still prefer to keep what sets Dwilight apart rather than uniformising it with the other continents, because I fear that the only way it can go is down.
