I think you're taking advantage of the weird disconnect between Yoda and the Clones showing up at the arena-- and then suddenly leaping into a giant battle with the droid army.

I never realized completely what I didn't like about that before. But now that you've unhinged the two events I know what it is. They don't feel like they're connected naturally.

How did Yoda and the Clones know about the arena situation and the giant droid army situation? From that little "email" they got from Obi Wan? It doesn't seem completely logical.

I like the direction this edit is going. It feels more likely that the rescue at the arena is when the Jedi would realize how big this Dukoo threat is getting -- so (as I believe you are saying) they have to regroup, get Clones, and come back to kick some ass.
