To me it seems pointless to have all of the stats add up to equal 80. Since we use allocation points all the classes can have the same 'power'. That 25'th point in intellect is worth much more than the 4'th point in charisma. You are treating each stat like it is worth the same value when they are not that way.
The Disciple build (Disc on live) - 262 left over allocation points
The Pyromancer build (Pyro on live. Thanks
@whiteninja1970 ) - 234 left over allocation points
Pyromancer uses more allocation points, and can be considered better.
That is the one of the main problems I see. The other problem I see is that these base stats do not really match up with the class that well. For example, Disciple has no need for charisma. Or berserker has no need for wisdom or intellect
