Great post, with very pretty graphs
You might clarify in the damage-->decay formula that damage refers to the amount of damage absorbed by the armor, not the total damage done by the mob. I've had some questions along those lines in my soc.
Oh, and the mob damage type thing is just insane! The Wiki will need a whole new setup to deal with that, I guess fields in the maturity damage chart for each mob. Now that the armor things is pretty well figured, maybe I'll help with that some.
