So your argument for why oopp should happen is, because you believe you deserve the right to shoot members of the opposing power?
Again, why is this strange? Why is it strange for an opposition army to want to attack supply lines? Why do you think its strange that by carrying something that helps your power I might want to stop you, if it helps my power to reach its goal?
That has nothing to do with making powerplay better as a whole, that's just expanding the aspects you, personally, enjoy.
In your opinion.
So what? You can't just dismiss aspects you don't like by calling them 'grinding'. People enjoy those aspects, and no matter how much you dismiss it as 'grind', uncapping UMing fixes the only real problem you've actually presented, with no relation to oopp at all.
Just look on the forum for your answer, people want content and not grind. Doing the same thing with the same results is not the same as actually using your skills and ships to the fullest.
Face the facts, none of the problems you've highlighted would be solved by oopp.
Unlike how I've explained in detail the problems of powerplay, and offered solutions and the impacts of those solutions, every question I ask you, you strangely never answer? All you say is 'it wont work, because'.
You(and others like you) would enjoy it more, but that's not relevant.
Why is it not relevant?
