I'll elaborate on Point 3. "Special Ability/Role pausing: Pausing and unpausing special abilities or roles won’t contribute to gaining additional attribute points."
The pausing/unpausing of Role/SA business was part of a lesser known way to abuse the system, similar in effect to the GK drill. The thing that made it work like that has been fixed. It is completely normal that Point 3 wouldn't make all the sense in the world for the players who did not delve into exploitative methods of play.
