I don't give a damn about this thread, this is just a continuation of your petulant need to spite KOTOR characters in your free time.
You are claiming that Sion, Traya, and Surik are fodder tier duelists because they don't have feats good enough for you to fallate over. Well la de da, nobody gives a crap what impresses you. We have accolades and statements good enough to put them on tier 7/8/9 as duelists
Next you'll be saying Revan is a fodder duelist as well I presume.
Surik and Traya loses in sabers only to Luke, Vader and Dooku, I admit that. Arethry stomped? no. Are they fodder tier? hell no.
I always saw the light, you are the one calling one of the greatest Jedi heroes ever and her nemesis fodder tier.
As for your proof that Sion can't be killed conventionally, here is a direct scan from the KOTOR:CG provided by Ant:
