I wouldn't call that EU. But in any case, the idea was the get Dooku killed because Sidious feared Dooku was being too ambitious. And with the war over, Dooku would have no reason to support Sidious anymore. Anakin won not because he was a superior fighter, but because from the beginning Sidious had planned his win.
Cuz they sucked.
Muskets were more popular than longrifles in the 1700s. Are they more accurate in a shootout? No. Don't argue stupid concepts like that. Makashi WAS the best, period. This was an excerpt from SW Insider from the creators of the forms. Their ideas trump yours, period. Dooku > Anakin.
I didn't ask who, I asked why.
Anyways, the reason why is either a) because they were fighting guys with guns, not other Jedi or b) personal preference.
Makashi is stylized for purely saber-on-saber combat. If you need a duel to be won, call in a Makashi practitioner. If you need to own some dude with a gun shooting at you, reflect it back with Soresu or avoid the shots with Ataru. Or...don't fight and die with Niman.
