So was Maul. So were everyone but Dooku, the Separatist Council, Grievous, Yoda, Mace, Obi-Wan, and of course, Anakin.
It's irrelevant.
She has feats. Nearly Force-crushing Kenobi and almost destroying the heart of a centuries-old and rather powerful Jedi Master, to name two.
Dooku was also highly impressed with her "raw talent," which coupled with incomplete Jedi training and her inconsolable rage allowed her to become the dominant force on a warring planet at a relatively young age.
Way to jump back into bed with Gideon. I am allowed to disagree as a mental exercise, to just calm down.
Maul was a tool to be used, Dooku was a tool to be used, so was teh Separatist Council, Grievous, Yoda, Mace, Obi-Wan and especially Anakin. They were all powerful enough or influential enough or skilled enough to factor into Sidious's plans. Maul was an enforcer, Dooku and Grievous were patsies, Yoda and Mace posed real threat to his plans, Kenobi warranted a Jedi Trap halfway across the galaxy, and then there's Anakin. The truth is that Ventress simply was not powerful enough to register as even a blip on Sidious's screen. Based on his judgment she was irrelevant.
I didn't say that she was weak, I said she was not strong. She has some impressive feats, but there is nothing that even hints at her being a valuable gauge of power for the elite tier. So Dooku can manhandle her. So what? Ultimately, this is not a very impressive feat for Dooku.
Her strength in the Force, or even her ranking on the tier system is not being debated. She is reasonably strong. What matters here is what Yoda meant when he said "Strong in the dark side you are. But, not that strong." I proposed one theory- that Yoda thought her very evil, but not particularly dangerous. This is supported by Sidious's disregard for her contributions and Dooku's manhandling- she is not a threat or measuring stick for any of the Saga's Elite.
Off the top of my head:
Maul:
Dark lord of the Sith
High end- Multiple forms
Took out Qui-Gon and Anoon (TEH SKILLZ)
Tanked lightning
"wizard of the force"
Mastery of Teras Ki (whatever- the Martial arts)
Sidious's enforcer
Ventress:
Jar Kai
Que'tek
Got manhandled by dooku
irrelevant to galactic plans (Sidious's)
I'll grant you that I was biased, but Ventress is not in Maul's league. His speed was great enough to challenge Sidious. I feel safe from fanboyism when saying he's at least (and I'm being cautious here) one tier firmly above Ventress. Maybe two. She's just not that good.
Grammar never hurt anyone. "The only force power that I have seen Darth Maul use was Force Choke. He used it to kill one of theBlack Sun.
This way makes you sound less like a hillbilly, and more like someone worth responding to. Give it a try, you too might find yourself Hooked on Phonics! (TM)
No Anakin uses two hands, and its sure as hell not casual, he kinda struggles http://www.youtube.com/watch?v=WmRaQIxqUh8
Oh and btw this isn't even Dooku using two hands lol, this is one hand dooku
