I think the best way to appease the quite understandable desire of those people that wish a lower power down time and an excellent compromise in my eyes is to do the following:
Reduce the power down cycle from 7 days to 5 days, just like it was done with delegations.
Reduce the amount of weeks/cycles it takes to withdrawl all of your balance from 13 weeks/cycles to 10 cycles.
This effectively reduces the power down time from 91 days to 50 days and gives you 10% of your balance per cycle instead of 7.69% per week.
