She could keep him entertained, or Dooku can multi-task and sprinkle some lightning his way. It's certainly within reasonable to assume Team 1 has the advantage. Ventress has a lot more kills under her belt than Opress by far.
He certainly roughed her up a bit, being superior in strength. But she's wicked agile and smarter by far, so she stays alive and can keep him at bay. Key thing is she doesn't keep herself directly in saber's length and can run like hell. In her battle with Anakin and Obi-Wan in the series, she showed the ability to use the terrain to her advantage and multi-task.
In any case, Dooku would fare better against Maul than Obi-Wan did, and Ventress doesn't need to dominate Opress for her team to win. Dooku and Ventress both have reputations for being savvy, agile, and using the Force intelligently, which is something the brothers can't lay claim to really.
In what limited exchange they had here, Opress brute strength'd both her and Dooku several times, so his Hulk rage factor is IMO the only edge he has over her. And even then, she can dance around him quite a bit.
I also could be biased, because I think Opress is a stupid brute and Ventress is an exotic femme fatale.
Oh no trust me, I super dislike Opress looking better than her. She should dance around him and cut him to shreds. Its just kind of hard to ignore her looking like shes on the back foot constantly.
I understand. I think she should come out looking far better. In fact, I think some of the EU novels placed her much higher (Dark Rendezvous, The Cestus Deception in particular).
Honestly after seeing Dooku's last CW fight against Anakin and Obi-Wan, I'd say Dooku does have a chance of soloing. Probably nto a great chance, but I'm sure he could take 2/3 out of 10 wins on his own.
Adding Ventress who can hold off Maul for a short time, and Opress for a lot longer, gives Dooku all he needs here to win every time Imho.
She held her own though. She was certainly losing, but never actually lost.
