Candidates for Tier 8 combatants?
With Anakin, Mace, Sidious and Yoda being confirmed for tier 9 status, and the likes of Luke Skywalker certainly being there as well, I'm curious to see who you'd rank as a tier 8 combatant. Again, we're counting all relevant facets of dueling (skill, experience, Force augmentation, Force reserves, etc.)
By Nick Gillard's measurements, Obi-Wan Kenobi, Darth Tyranus & Darth Maul all fit into this tier. This is likely to be a rather expansive list (since the tier is quite big and not everybody in it is equal).
Since TPM Kenobi is confirmed to be tier 7, and Qui-Gon is just a tad above him, I'd rank Qui-Gon near the top of tier 7 but not quite in tier 8, yet.
So my candidates for tier 8 would be: Darth Vader, Rebels Ahsoka, RotJ Luke, Ven Zallow, Aryn Leneer, Darth Malgus, Sora Bulq, Darth Tenebrous, Jaina Solo, Kyle Katarn, Mara Jade Skywalker, Ulic Qel-Droma, the Hero of Tython, the Emperor's Wrath, Meetra Surik, Darth Malak, Darth Bane, Darth Zannah, Savage Opress and Asajj Ventress.
All of the notable Ancient Sith fit in here as well.
Not too sure about Jaden Korr, Darth Nox or the Barsen'thor, but they're all possibilities.
