Nope.
It's a "slider" with specialisation at one end and choice at the other.
You increase one and you decrease the other.
Course, that's not to say it wouldn't be a good idea to adjust things one way or the other.
A little more specialisation might present people with interesting decisions to make.
Conversely, a little more choice might do the same too.
Well, I'll disagree about things being such a bleak two-dimensional box, but I am *all* about reaching that balanced middle ground. You're quite right that one must be careful of going too far either way!
