I really dont understand this? From what your saying, you will max fire mastery before you max fire bolt
Lets assume a lvl 99 es fb sorc ( with precast so 5 in energy shield ) with standard build ( so +28 skills i believe ) and 1 pt warmth
at level 99 you'll end up with 20040-21600 dmg with your method i believe ( you can double check this )
however with maxing fire mastery last and putting more in synergies first you get 20423-22013 dmg which is clearly better...
I hope I've misunderstood something tho, as it looks like you've put a lot of effort into this so wouldn't want it to be wrong, but also dont wanna give players wrong info

Edit: Looking through the posts again, I get the feeling that it wasnt really meant for a pvp es fb, but for pvm - so the less + skills you have the more your method works, i.e. assuming 0 + skills maxing mastery before synergies is indeed better. But as you get more + skills the effect of putting points in mastery diminishes as opposed to synergies ( as synergies aren't affected by + skills ) and with a higher +% dmg from mastery already the next 7 % will add less of a percentage gain naturally...
