The poll was titled 'When should this world be closed'... now, the way I see it, that wording is not crystal clear. It could either be seen as 'when should the world be closed to new joiners', or 'when should the world end'. Since one of the options was at 100% dominance, any logical person would assume that it meant when should the world end, since it would be impossible to attain 100% dominance while the world was still open to new players.
So I'm sure that many of those who voted for 100% dominance were under the impression that at the very least the world we be closed to restarts and new joiners, so that 100% dominance is actually possible.
If you are seriously considering not making any changes because of the results of this poll, then you need to give your head a shake. At the very least begin a new poll with options that actually make sense.
