He has spent 80 years mastering Makashi.
And Sidious ahs only spent what? Around 60 years mastering Ataru and he could take Dooku. Bane has spent less than a year studying Djem So at the end of PoD and he could at
least give Dooku and great match. So your ideology that Dooku > Maul cause he's been studying his form for longer is flawed.
He has been taught by both Yoda and Sidious.
Oh, and Anakin's been tuaght by Kenobi, who is inferior to Yoda and Sidious, yes Anakin pwnd Dooku! ZOMG!
I said relatively weak. He is Force sensitive and so has power in the Force. It just wasn't his strong point. He was a swordsman first.
Agreed, he was a swordsman first, but he was NOT weak with the Force. He had used Force Choke, Grip, Speed, Jump, Push and resisted Force Lightning just to mention some of his feats.
And no, TPM Maul and Qui-Gon could not defeat ROTS Anakin and Obi-Wan, Maul could hold either of them off for a little while, I guess, and Qui-Gon vs. Kenobi would be drawn out due to Soresu so a battle between the two teams might last as long as, oh 3-4 minutes but the ROTS duo definitely wins.
