I don't know if anyone will ever see this (considering the thread died 4 years ago lol), but I found the mistake that made default weapons seem overpowered when using the spreadsheet.
On the cell that calculates the total (D5), it sums up the total values of all features then subtracts 1, instead of adding 1. This essentially means that instead of starting with 1 free point, you start off in the negatives.
The fix is pretty ease: just make that "-1" at D5 into a "+1" (or even just a plain old "1")
