it must be new because even in the link u provided in the first paragraph under powers it has a quote from lucas saying this. "From then on, he wasn't as strong as the Emperor—he was like Darth Maul or Count Dooku. He wasn't what he was supposed to become. But the son could become that."
The quote doesn't preclude the idea that Dooku and Maul couldn't become more powerful than Sidious, just that they didn't.

I'm not sure what u mean by they werent part of banes sith order. Lumiya was an apprentice of Vader that he was going to use to overthrow the emperor, she was a firm believer in the rule of two and trained jacen under the rule of two philosophy then jacen chose tahiri as his apprentice. it might not be the strongest link but they're still connected.
Bane's order died with Vader and Sidious. Lumiya was not formally trained as a Sith; she has no more claim to the title than Ventress or Starkiller. That she adopted Bane's numerical limitation on dark siders doesn't translate to an ultimate advocacy of his teachings. We know, in fact, she defies Bane: laying down her life for Jacen rather than forcing him to wrest control of the order from her. But more importantly, Lucas has no involvement with post!ROTJ EU "Sith." Bane and the Rule of Two, on the other hand, were directly conceived by Lucas in the background of The Phantom Menace. Whether or not he meant his words to apply to Lumiya, Jacen, etc. is unknown but unlikely: he doesn't consider them to "exist" in the strictest sense.
