As usual, Samira said things best.
It is inconceivable to me that anyone who calls themselves Amarr would dissent against the Sacred Throne. Maybe there were grumblings when Emperor Heideran VII declared peace with the Minmatar rebels, though I can say I don’t remember any spoken, even in private, to me. And such a public display would have been unfathomable.
If the Amarr Empire didn’t need capsuleers, I would say to get rid of them. The power has clearly gone to the heads of many. Baring that, I would like to put all of the Empire’s capsuleers firmly under the control of the Sacred Throne, not CONCORD. Again, not really possible, but a woman can dream.
