How can you champion Bane and lowball Sidious?
Since my previous thread got closed because apparently "wanker" is a bad word, let me rephrase my question.
Here's a case study:
A certain supporter of the Bane era claimed that Darth Zannah could defeat Revan.
That same supporter then claimed that Revan could defeat or match Plagueis.
How is this possible? The fact that Bane is the weakest of the line is explicitly stated in at least two Legends sources, so Plagueis has to be more powerful by thirty successive power creeps. And we know that these have to be substantial enough for a significant portion to have been the apprentice beating the master in single combat before their primes, and then seemingly growing more powerful on their master's deaths (as Plagueis and Sidious did). Then Plagueis breaks beyond that by manipulating his own midichlorians and shifting the balance of the Force.
There's a logical disconnect between saying that Bane is a Vader/near-Vader tier combatant, but that Sidious would lose to novel Vitiate or something.
