Just say the devs can never untangle the spaghetti code and the character customisation will never improve significantly... would you use an external OFFICIAL character customisation app that you can import into the game? (Imagine something like the benchmark but just for making your character.)
I've heard people have copied dat files to/from the benchmark to see truer representations of their characters, and it got me thinking about how that could potentially sidestep the in-game code.

Thoughts?
