Some members are Vader Fanboys; they don't like the fact that a weakened version of Obi Wan is probably the most viable combatant he's faced up until A New Hope. For the thread, no visible evidence that Ben closes this gap in the Force, only illusions to how connecting with the spirit realm would have hindered his access to the physical.
Show me statements that he was a serious challenge. Statements also state that Dooku was a near-equal to Yoda. So I'll take that.
Anyways, depictions of events > statements. 2 sources depict Obi-Wan not being a serious challenge to Dooku (the film and the comic, plus TCW S6 if you want to count it due to proximity to RotS), and only 1 supports Obi-Wan being a "serious challenge", which is the novel. I'm siding with the majority.
You know which source. By replacing the word threat with challange you think you can circumvent it? And the Yoda quote doesn't overwrite it.
The movie is too vauge, you can't decipher from it if he was a threat or not. TCW doesn't count because of pre-prime. So you have 1 source vs 1.5-ish. The junior novel notes he can counter Dooku's choke (I know you stance on it so let's not get into this again), which is something I would expect from a threat.
Anyhow I'm getting sick of debating Kenobi vs Dooku with you, so make your rebuttal idc 🙂
1. The fact that Obi-Wan was a threat to him doesn't make him a serious challenge. Kyle Katarn was a threat to Caedus. Do you think that made him a serious challenge? Evidently not.
2. The movie has Dooku controlling Obi-Wan's saber. Obi-Wan never comes close to hurting Dooku and is dismissed three times by either Dooku's saber or the Force. Countering Choke doesn't change anything.
1.5 is still > 1, but it's 2, anyway.
