Just look at the C-Hog before it was perked for an example of an "undesirable effect" on game play.
ack-ack
Before there was a XVI in AH? And is the unperked, pre XVI C-Hog the standard? If it is, then we can't explain why the XIV is perked, because it would never reach that kind of status.
I know I'm being a pain in the ass. I'm just trying to point out that what is perked and what is not seems entirely ad-hoc, with no real criteria to determine it.
Unperk the C-Hog!
