Tau Idair vs Savage Opress

all-out

Savage. Tau's feats are kind of lackluster. Her plus numerous Jedi and troopers briefly held off Malgus and the Outlander, and per her own words Malgus alone could have killed her and Arn.

Tau being better than Malgus isn't enough to beat Oppress.

Tau Idiar is far stronger than the likes of Savage Opress. Depending upon the choices made, Tau could destroy that skyscrapper as well. 

She is much humble in her opinion. Do not fall for it. 

She was a veteran of the Great Galactic War as well as The Eternal War. She is no less of a legend than others - among the very best of Jedi. A survivor with significant muscle.

Savage is next to nothing in comparison to the likes of Darth Malgus. Just because he beat some Jedi does not make him Darth Malgus TIER. He was still much less of a Sith.
