You have to admit elves have such a better head start then humans do, remember when Rhunon is making Brisingr through Eragon and the only two children come up to watch Rhunon staes something along the lines of "Elf children are blessed with gifts of grace, strength etc."

And who was it that said that an Elf rider wouldnt gain much from becoming a rider? I find it hard to believe that they wouldnt. All beings grow in strength as they get older, espeacially when theres no limit set since there everlasting.

Haha ok you got me.. sure a human's power will rise more in comparison to his fellow beings i'll give you that, however elves were already Strong with magic and such before the pact with the dragons otherwise they would have been WIPED out during that first war between the two, if the dragons (before the pact was made) were to attack the humans im including all of Galby's army. id put my money on the dragons.

Dont you remember when Brom stated that even the weakest elf could tear Eragon apart (before the Agaeti Blodrhen of course). Do you think that Brom could defeat a elf? He lost his dragon sure but even still he must have retained some of it.

No im pretty dead set on elves being the clear choice.. Galby and Vrael fought and Galby had many eldunari by that point, if it wasnt for Vraels hesitation and Galbys underhanded blow Galby wouldnt even be ruler right now.
