How will spell power work in Classic?

Still looking for confirmation on the supposed value of specific spell power vs regular spell power? has anyone been able to test this?

this is a meme and its not true

the confusion comes from item budgets. greens with only +school dmg will USUALLY have more of a +value than an ilvl equivalent with +spellpower. Since +school dmg only affects the one school, it has more of a budget on that particular school.

+10fire and +10sp increase damage exactly the same. this is a meme that needs to die because I see people in game bring it up constantly

Glade you get it mages just have start lowering SP for a mana pool to cast none stop I ran into having to much mana
