Necromancer!
My version of strengths and flaws:
Mace Windu:
He was a great fighter and added a good perspective to the Jedi council. His weakness was his his short vision of the universe and Anakin.
Yoda: Great wisdom and fighting abilities.
Dooku: Oversized ego and pawn of Palpatine, Count Dooku was part of the real start of Anakins fall with his forced execution aboard Grevious's flagship.
Malak: Arrogant and cowardly, Malak had no great strengths beyond his fighting capabilities.
Obi-Wan: A great light jedi. Good fighting, good strategy, and pretty good wisdom. Weakness, the thought that he could keep Anakin away from the dark side and the fact he didn't say anything about the Padame affair.
Darth Vader: Average overall but with weaknesses like Malak's and his over confidence.
Revan: Supreme strategist and good wisdom, superior fighting capabilities, weakness in the fact he relied on good intentions rather than the jedi code, similar to Anakin.
Nhilus: Overconfident power hungry fool.
Sion: Not your average Sith, he showed some compassion and mercy. A good fighter, his end was similar to Darth Vader's, finally seeing the light again.
Traya/Kreia: A gray jedi seemingly but sith at heart her motives and techniques to carry them out were quite clever. Her weakness was the fact she had no real power over the exile other than insight.
Qui-Gon: Excellent teacher, likely better than Obi-Wan, he had a great fighting ability. His weakness was double-bladed lightsabers.
The Exile: A follower-magnet the Exile's is similar to Revan, however no so bound to any destiny. She couldn't be controlled even by Traya.
Jolee Bindo: Wise, gray jedi, Jolee's weakness was his strict adherence to grayness.
Bastila: She is a puppet waiting to be puppeteered and is overall weak. Her strength is her Battle Meditation.
Maul: His weakness was being double teamed by Obi-Wan and Qui-Gon. His strength was his double-bladed lightsaber abilities.
Grevious: Weak lightsaberman and arrogant. Strength was his army.
Palpatine: Better manipulation than Traya, his strength was his dark wisdom and weakness the goodwill of a true jedi.
Luke: A true jedi and follower of the light. Possibly graceful but often aggressive fighter, Luke isn't necessarily too wise.
Bandon: A show-off and weak sith.
