106 voters have used up their precious single wish to send a very strong signal that their paramount concern is with the dance-off. But how would the forum have divided over the alternatives?
No more dance-off, as proven in SCD1-4 and DWTS,
Stop dance-off at the Last 3,
Stop dance-off at the Last 4,
Stop dance-off at the Last 5,
Stop dance-off at the Last 6,
Stop dance-off at the Last 7,
..... etc
Stop dance-off at the Last 12.
There is no experience of the 10 new scenarios, and guessing will be the order of the day. If to be scrupulously fair to all views, 25 wishes were offered for choice instead of 15, I fear the forum will appear hopelessly fragmented, with no indication whether every voter will fight her corner to the death -- no change unless it is my choice. The Beeb could justifiably ask, can any two of you agree? The judges will laugh. If we are divided, they will conquer.
As it is the forum has united behind the strong signal that the dance-off has to change. Detailed implementation of change properly belongs with the Beeb, and I doubt they will accept dictation from this forum. No decision will please everybody -- hopefully aiming for the greatest happiness of the greatest number.
