I agree with a lot of what you said. I do not really like the comparisons they have made with the classes to movie characters with respect to the Jedi classes. They say that Obi-Wan and Yoda were consulars, and yet Yoda was the best swordsman in the galaxy and Obi-Wan as at least as skilled as Anakin at lightsaber combat. Same with Qui-Gon, you don't really see him use many force powers, and he could hold his own against Darth Maul for a while. I see what they mean where Obi-Wan and Qui-Gon go on diplomatic missions while Mace Windu kills guys, but no so much about combat. I also don't like how they named the classes, while Jedi Knight does sound cool, it is not equivalent to Consular, all Jedi above padawans are Jedi Knights but Consular is a specialization.
I'm writing up a "what we have learned so far" post from all these previews, so if you are too lazy to read them all, look forward to that later today.
