For the final time, ignore Nebaris. He relies on misdirection, lies, and double standards. Do not respond to any of his arguments. Period.
Edit: Dooku and Maul tool the shit out of Traya and Sion for reasons already mentioned, but if Traya is allowed use of her 'instakill', she would likely win the Force competition. As for Dooku's proficiency at Dun Moch, it's been pretty much mentioned in every damn source in which he's been featured. He's unleashed it against Anakin Skywalker on three occasions, Obi-Wan Kenobi twice, Asajj Ventress, etc. The Count is legendary for charisma, which is only enhanced with his impressive command of the Force.
