Darth Bane and Darth Zannah vs Darth Malgus and Hero of Tython

Yeah, I mean not factoring in Bane was protected by night impenetrable armor and wasn't even actively helping Zannah or anything to suggest viable teamwork.

Team 2 is better in everything barring Sorcery, Bane without orbalisks is trash

Instances of Malgus doing anything that matches Bane's peak speed and saber skill? Instances of Malgus or the Hero showing that they could penetrate Zannah's defenses? If they can't even do that, they certainly aren't going to survive a full onslaught of sabers and Force ability.
