Specifically a hack that lets you keep Dark Knight Cecil throughout the game. Obviously with rebalanced this and that, item changes, etc. But still, that kind of blew my mind. I came on here looking for that specifically because I figured SOME talented, awesome, attractive person would have done it by now. I mean I know I'm not the only one who's wanted to finish the game with DK Cecil instead of Paladin. I'm always really disappointed when the class change goes through. I just don't like Paladin Cecil. I know pound for pound he's more useful strictly by numbers, but it doesn't FEEL like it. I never use his cover ability, and his white magic I feel like is only good in the most dire of emergencies. He's just an attack button with some HP attached to it. Yeah DK Cecil was more or less the same thing but I really liked the whole 'dark wave' thing. It was cool as heck and fit my personally more offensive based playstyle.
I don't imagine this would be too terribly hard to do. Change the class change event, bump up DK Cecil's mid-late game numbers, redo all the Paladin items to be usable by DK Cecil, and redo bits and pieces of the script. Hmm. Maybe this wouldn't be a half bad first hack for myself.
