It's just one of the many reasons as to why I loathe Cid. It'd be interesting if there was more depth to his defection, such as him being forced to face the reality of selling enemy secrets and getting the loved ones of his people killed as a result. The deepest reaches of hell are said to be reserved for traitors simply because how how despicable they are - yet too often in stories like this they're branded heroes. Regardless, Garlemald has been making considerable advancements in regards to Magitek over time - Cid being able to deal with everything Magitek related really just shows him for the convenient plot device he has become.

I'm inclined to agree with Kallera. There's little point in dragging out a 'war' if the war itself isn't going to actually amount to anything meaningful.
