I don't so much mind
what happens during the storyline just
how it happens in the portrayal. The killing of Rhaegal and the capture and execution of Missandei will work well and drive the storyline forward (I'm guessing these in particular are towards an eventual 'madness' of Daenerys), but they were just not portrayed as well as they could have been. These are key plot points but I, even as a dilettante, think they fall far short of how such important moments in a storyline should be portrayed
Also, those ballista were OP. Please nerf in the next patch
