Thought I'd had some more.
5. The big legs need to go. At-AT- and at-st make some (small) sense for navigating bad terrerian, but wouldn't anti-grav since they use it elsewheree? Maybe that would save power? I know it would change how the gliders take the AT-At's down, but it'd like to see them at least be able to fold up and the things fly in launched from the ships above.
6. Sheilds or no. IF x-wings have them, so should the ties, or vice versa. The rebels should be poor I don't see how they have better shields than the Empire.
7. More Rebels on Endor, fewer reliance on ewoks.
8. Better death, I mean shoot out death for Boba fett. That death needs fixed!
9. The old trilogy saber fights do need some improvement, not necessarily tot he ballerina point of the prequals, but still better. Vader needs to be more flexible and ruthless.
1. Could happen to anyone, if you were seperated at birth and had no clue she/he was your brother/sister.
2. 3P0's made for protocol and translation, he's not made for lifting, moving or doing karate, he's basically just a mobile computer. So he doesn't need to be more mobile.
3. Luke was on Dagobah for at least a week. He was so strong in the force that things came easily for him. Plus, when he leaves Dagobah in ESB, his training is not complete.
4. This is how things went down in the Expanded Universe. Besides, it would've been strange for the last chapter to end the way you describe.
5. The AT-AT's were pretty much for visual show. They work as is.
6. The Emperor/Empire considers TIE fighters and their pilots expendable, so the TIE's are made cheap and fast. They're made to swarm and outnumber. X-wings and Rebel craft in general are built to last due to the Rebelion's limited pilots/resources. They're not as expendable.
7. There where limited Rebels on Endor cause that's all that'd fit on the shuttle. Plus it was a small commando force meant to go in, do the job and get out. They weren't expecting a big battle. Plus, the Ewoks kicked butt, get over it. The Ewoks took the Empire by surprise.
8. Fett was a wuss. Only in the comics and such is he a bada__. Plus his death is even funnier because you expect a shootout/battle of some kind and instead Fett is killed off hand in a hillarious fashion. Awesome.
9. The sabre fights were perfect.
