I believe what you are asking is why is it that the total stat allocation for something like celestial as opposed to something like dragons or berserker. The reason is because of how the compounding effect of stats work.
For example take berserker which is power, critical chance, and critical multiplier. Having an X amount on each of them is good, but having the same amount X on all of them at the same time is significantly better. That is because X power increases your damage, X critical multiplier increases your critical damage which is based on your X power, and X critical chances makes sure your critical damage procs as often as possible. Meaning you are triple dipping into the X number.
This is not the case for stats that affect differen kids of skills. For example having X vitality, and X power affects your caracter separatly and does not have the stacking effect from before.
To balance these two effects the more attribute distribution you have less point on each individual attribute (for the first point balance) but you have more total points (for the second point balance).
To test this you can compare celestial to berserker and you notice that for a particular piece, chest for example, as you noted the total number of points is more. But it has less ferocity, less power, and less precision.
