Which is where Moonshade comes in yo
I'm confused. Did you want the "overflow" Store TP explained (which is what you asked for clarification about) or did you want an excuse to try to justify an inferior piece of gear selection?
I'm not 100% sure on these numbers, because I'm not checking them, as I don't even like doing math for my own gear, let alone for other people, let alone to do it just to prove someone wrong on top of that.
Bottom line is your overall numbers are going to come out ahead with a solid, non-regain-earring dependant TP set and TP Bonus Moonshade (again, excluding 100% monk players, if I remember correctly.)
I'm pretty certain that's been mathed out about 50 times - minimum - in other threads.
