Every class that wants the extra points has to build the stat specific to their class, that's not build diversity, thats build homogeny.

Full agree on this point.

If, say, an MA wants that extra skill point they are forced to put points into CEL, even if they otherwise aren't using CEL. You are being incentivized to build a particular way, getting more for building the way the game wants you to and receiving less for going against the grain. For this to promote diversity, the two options would have to be equivalent on some level and they are not.
