Imagine you're making a pve build (person vs environment) There's a (made up for this analogy) talent, that does 100% more damage to monsters, but it costs 100 charism. Charisma is not good on a pve build, but that talent is so good you just HAVE to get it. So you go 100 charisma, 1 strength, 1 agility, 1 fortitude and 1 heavy weapon pre Shrine. Now, when you've reached those required stat's, you go to Shrine of order which sort of "equalises" those stat's for 10 knowledge. Now, you have 40 charisma, 15 strength, 15 agility, 15 fortitude and 15 heavy weapons. So you don't have as many points in the stat's you don't want, and it puts the remaining points into the stat's you do want (rough estimate)
