How much of a factor does physical ability play in a duel?
I saw this pop up in the Bane & Zannah vs Kenobi and Anakin thread.
This seems to differ between Disney Canon and EU
How much of a factor does a force user's non-augmented physical ability play in duel?
Personally, I believe that the more powerful the force user, the less significant physicals become. The reasoning behind this being that a more powerful force user can afford to continually "waste" more energy passively augmenting their endurance, strength, speed, etc than a mid-low tier force user. I'm talking simply about passive biological abilities. Not bursts of speed or strength.
Why is someone as powerful as Dooku, who's described to be in better physical shape than humans half his age, inclined to maintain their physicals? To contradict what I just said a paragraph ago, the RotS novel states how Dooku was affected by his physical handicap as he was forced to lavishly spend his force reserves fending off Kenobi and Anakin.
In canon, Dooku's fight against the night-sisters left him coughing and wheezing near the end of the battle which was then exploited by Ventress. Was this due to Dooku quickly fatiguing due to his age, or was he simply exhausted as a force-user (the latter seems less-likely as we see him electrocute the trio and throw them out his window)?
Propose ideas here for both canon and EU.
