Nyriss's charring/incinerating people was also on a Nexus. 😮
Anyway, Revan does have quite a few combat accomplishments to his name. As a duelist, he's highly skilled in multiple forms of lightsaber combat (We've seen him using Shii-Cho, Ataru, Shien, Niman, and Juyo) that has Echani-level precognitive abilities, and is an expert at chaining force attacks into his lightsaber sequences. With these abilities he has proven his capability in combat in his defeat of Darth Malak, Mandalore the Ultimate, and he cut down dozens of Dark Jedi *totallllll* on the Star Forge. With the Force he's just as accomplished, having been noted several times as having an astonishingly powerful command of the Force, using TK to collapse stone arches, hurl Vitiate, ragdoll fodder Jedi, and use a protection bubble to protect him from grenade blasts. He's also proficient in other abilities, especially Tutaminis which he was able to use to bend back the lightning of an amped Nyriss, and Force Healing/Force Lightning/Force Scream. He also has an immense wealth of knowledge on Dark Side Rituals like language absorption, thought bomb, Bane-ritual-thingie, etc.
Now, that all being said, it doesn't really make him better than Anakin or Vader at all, even if Ant wants it to. However, it's undoubted that he's an extremely capable Jedi Warrior, and I see no reason why he couldn't put up a fight against Anakin if Ventress or Barriss could do the same.
Ultimately, Bastila's only really useful for Battle Meditation, so this is Anakin and Ahsoka vs amped Revan. Now, it is my personal opinion that Anakin probably has a chance of soloing even an amped Revan, and with Ahsoka at his side the battle is pretty well in Team 2's favor.
This will be a close fight, though. Revan+Battle Meditation is no ****ing joke.
