I'll leave your communcation for Rmorph to respond; however, I would like to say one thing.
Limiting usage of capital ships by rank has never worked; if someone has the means to get a capital, and wants the experience, they simply just have to create an indie character. Direct limitation of caps by rank will never work.
However, it is reasonable to take the stance pushing a requirement of a certain experience level before being allowed to engage in a cap ship; this will stop 'cap stacking', and limit the amount of ships that are just cannon fodder. In addition, it allows people to learn how to work well, as a unit.
Of course, those who don't wish to follow this can just go indie, and that is quite within their rights; however, such an approach is clearly far more logical, and the majority will understand that training can only be a good thing. Therefore, less will be pushed away and we'll have less lolwuts, especially those in ECG.
Just something to keep in mind, while pondering solutions/ideas.
