Prove that either of them are stronger than Revan.
Bane pulled a fricking moon out of orbit. Saberwise, he has much more going for him, considering he was basically on par with Kas'im, who's been proven to be uber. He also possesses orbalisk armour, making him almost physically invincible.
Exar pretty much mastered sith magic almost instantly, his amulet blasts and his mastery over them are incredible (they can be defended against, but not easily, and it doesn't drain Exar of energy), he effortlessly froze roughly a million senators.. Exar also has much more going for him saberwise as well, considering he was slightly better than Ulic, who was able to stalemate a very power jedi who was tapping into the darkside of the force, while cut off from the force and decades out of practise.
I'd say it's safe to place either above Revan.
Especially when Bane's knowledge is, apparently, nowhere near on the level of Revan's own.
Knowledge isn't everything, and both posses enough of it.
Again, Yoda can dodge them.
No he can't, his speed is way over hyped, and the blasts are of too great a magnitude and too quick for Yoda. They're also continuous, and they don't drain Exar of energy, Yoda can't run forever.
And when has Exar shown to use his blasts in a fight? Sorry.
He never needed to.
Bane can't generate the blasts, so it'd be Exar.
Did I say Bane could?
Vaapad > Bane's style. Bane doesn't know Vaapad. There's nothing to indicate that he could defeat Mace in a lightsaber match
1. Forms really don't mean that much, and Vaapad isn't that much different to Juyo, only a few improved manoeuvres, the major difference is mental.
2. Bane proved himself to be as good as Kas'im at the end of PoD, and it's been proven that Kas'im >>> Mace in saber combat.
3. Bane's orbalisk armour makes him almost invincible in saber combat.
when the form itself is a super conductive loop against dark side energy,
Based on one vague line in a novel? Please, that situation has been completely blown out of proportion, Vaapad really isn't that much more effective against darksiders than other forms are.
and please, Yoda is more than capable of handling Exar - whether it be to keep him at bay or kill him.
Exar is leagues above him with the force and with the saber, and Yoda can't defend against his awesome amulet blasts. Yoda's getting pwned.
They're not going to make it to Sidious, and even if they did, neither of them are as powerful as he is on a good day. He'd crush them.
They'll make it to him, in not too bad condition, and they'll win. Sidious can just beat either one, alone, but together, they comfortably beat him.
Also, need I mention that Bane's orbalisk armour almost perfectly protects him from physical damage, meaning he won't wound, and constantly pumps adrenaline into his body, meaning he won't tire. Bane also developed a lightsaber resistant mask, so his head is perfectly protected as well.
