I think I'd make Vayne a bit more nuanced at the end, i.e. more bent on helping humanity - including Dalmasca - get rid of the Occuria and less the mass murderer wannabe. It just got too cheesy.

The entire "freeing men from Occuria" plot was a very interesting twist and very creative IMHO but it got mishandled on the execution. Vayne was made - particularly in the end - as the cheesy 2 dimensional "I want power" clichee bad guy and Cid was made into a loony bin.

Judging by Cid's son the Doctor had been a smart wise guy once, and he was a scientist. Hard to believe he would turn into that lunatic from Pharos tower.

Gabranth was the only convincing, non cheesy villain IMHO.

Ashe's turning her back on people who risked their lives for her was the height of bitchiness to me, that is another thing I'd change
