Even if not easily put down, a pretender rebel remain a boring thing when the event could be so much more interesting (like, say, a genuine civil war)
I certainly hope the War of the Rose event is more than a pretender rebel popping with a slightly different text, if the goal is to add actual extra flavor to the countries.
While its understandable to drop the Shogunate system, it is rather diapointing as simply playing a unified Japan from the start of the game
No one from Paradox has said it will be a unified Japan.
Of course it is more than that.But the War of the Roses is more than that.
