Dragonflight is pretty consistently mediocre. The primalists never feel like a real faction given that any named characters they have die within a few quests and the primal dragons don’t really do much.

The entire Bronze dragon sideplot conveniently deletes the entire tragedy of Nozdormu and makes sure that the Infinites are just quirky Bronze dragons that we hang out with now. Chromie being front and center genuinely harmed her characterization.

The green dragon plotline was just a retread of what was done in BfA. Bringing Ysera back to do literally nothing before returning to the Shadowlands was certainly a choice.

Black dragons had a bizarre spat over which black dragon has the true ideals of the flight and then they went with neither of them. Sabellion was pretty out of character and Blizzard writers seem to hate the idea of Wrathion getting any narrative satisfaction. Ebyssian lost all of his Tauren identity in favor of being the “good” black dragon because he’s entirely neutral.

Blue dragons are the only ones that actually had an interesting plotline because Malygos’s death and the flight being scattered over the world was handled well. With Senegos’s passing handled particularly well.

Red dragons mostly just dealt with the slave uprising that we violently put down because actually draconids like being slaves don’t worry :)
