Two World Champions allow for the development of more stars and allow for both house show circuits to have championship matches as main events. I see no problem there.
Ryback definitely deserves to be World Champion, purely based on how over he is. One could make the argument that he should have been already.
The divas division still could use improvement, but the introduction of some actual characters to it this year has been a good start.
I agree with most of the rest.
