Let everything be moddable!
Simply put, leave as little as possible hard coded to allow for an almost fully moddable experience: Fully moddable UI, fully moddable class/race/multiclass/kit screens... the list goes on!
This would help the game live forever!
I doubt anyone would disagree with this sentiment of almost full mod customization capacity.
