4 or 5

6 tbh

Done at 6, even with Atris.

R1: Stops at 2 or 3.
R2: Stops at 3 or 4.

Darth Traya is outgunned at higher levels (in the conventional sense) but Force Drain remains an effective trump card.

Additionally, Darth Sion can resurrect himself again and again to harass his opponents.

The above being the case, the KoTOR 2 era Strike Team will experience its first real challenge at round 6.

Possibility of defeat from 6 and onwards becomes strong.

Sion won't be endless resurrecting off a nexus like in game. Besides, Carthage didn't say he could, so I don't see why you think he should.
