The strange thing is there lots of built in examples kind of breaking the rule. Such as Density Increase only costing 4 pts per level, so at a lot of breakpoints the active cost of Density Increase breaks the DC limit. You end up getting more strength than you can use in a punch. Just seems strange.
Also, another weird one is Ripose from the Fantasy Hero book:
Game Information: Trigger (when character is
hit by or Blocks an enemy’s attack and wants
to strike back, activating Trigger takes no time,
resetting Trigger is a Zero Phase Action; +¾) for
up to HKA 4d6 (45 Active Points); OIF (weapon
of opportunity; -½), Requires A Sword Tricks
Roll (-½). Total cost: 22 points.
Why is the 4D6 HKA only 45 points here? Shouldn't it be 60 active points?
Of course I realize I'm probably just reading too much into the details, but, just trying to understand how it works.
I do agree that the active points limitation is a nice tool for setting world parameters, giving both the player and the GM some stability in this extremely open ended system.
