Is a fighter able to select more than one Advanced Weapon or Armor Training option? The description of Armor Specialization would seem to imply that they can, but the fact that each ability scales would seem to imply not.
In the case of say, Armored Confidence and Armored Juggernaut, which case is correct:
1. Select Confidence at 7th, Juggernaut at 11th, get full 11th level bonuses for both.
2. Select Confidence at 7th, Juggernaut at 11th, get only 7th level bonuses for both.
3. Can only select one at 7th, which scales according to the description.
If #1, it would be a nice way to buff the power of the fighter at the higher levels where it needs it when compared to casters and zany basic classes from the various power bloat books that have come out in the years since Core.
