Pg 51, MW 2nd Edition, we had "Every time a character rolls a 2 or a 12 while attempting to use a skill in the course of play, he will earn 1 Skill Point for that skill."
Has this been totally removed with 3rd Edition and AToW? (by nature of explicit rules, beyond "If the GM allows it").
And yes, I do know of the "hash-mark tag a skill when used" method of 3rd Edition, and AToW's XP-discounts through Training.
