Oh boy, math!
I've yet to evaluate this thread, but I can already see major flaws based on the graph alone.
First off, DPR isn't the only measure of damage. Its the expected value but its not the only significant data analysis for damage. I've discussed a bit on the "The Mathematics of D&D" thread I posted a few weeks ago but I'll try giving a more thorough analysis when I'm afforded the time so we can truly determine whether a monk does have a place on the team as a type of damage-dealer.
I am intrigued. Can't wait to hear your thoughts on this!
