Good list. Some names I don’t recognize and some placements I would change:
-Loras and Brienne should maybe be higher imo…. Loras should be pretty close to Jaime as Jaime praised him heavily, and Brienne beat Loras in a melee.
-I would move Barristan up a tier. Maybe Jaime as well.
-I would move Gwayne Corbray down a tier. His dual with Daemon Blackfyre is legendary but that is also his only known feat. I don’t know if he deserves to stand up there with Dayne especially since Daemon did win the dual.
-George actually said Daemon the Rogue Prince was the most experienced warrior of his time, not the best, I just looked it up on the Wiki:
Daemon was the most experienced warrior of his time and wielded the Valyrian steel blade Dark Sister.
However I would still put Daemon that high as a martial Targaryen who fought personally in multiple wars.
-Gregor would go up a tier for me.
But a good list nonetheless.
