Out of sheer curiosity I started playing with the character planner on Net-7.org
JE, JD, and TT require 412 skill points to max every skill out, that's lvl 150 + 136 skill points (so using the 136 "extra skill points" as a standard, I did a little research on who's missing out)
JT maxes out everything with 54 skill points left
TS maxes out everything with 44 skill points left
PP maxes out everything with 36 skill points left
PS maxes out everything with 15 skill points left
TE maxes out
