Can Admins pretty please just pin one of these umptillion threads about lowering the province threshold? That way we wouldn't have to rehash the same argument every time somebody suggests this yet ANOTHER time?
1. Reducing the province threshold doesn't magically create more kingdoms, it creates more leaderless nubs. Because while players are important to a kingdom what you need is leaders. And lowering the province threshold doesn't magically create more leaders.
2. Yes dropping it from 25 to 15 or 20 overnight would lead to an exodus of players, doing it 1 province at a time per age it might work, assuming that you resolve the aforementioned issue of a lack of leaders.
Creating more kingdoms without leaders just creates more farms, and farms gets forced out of the game because they get farmed time and time and time again without being able to do anything about it, and so they quit to go play something more enjoyable.
