being below 75 int/wis and mana

[Jauna]

This fell into a few different sub forums so why not use general chat.

Does being under 75 Wisdom hurt Paladins or Rangers that much?
I know being under 75 agi hurts ac
I know being under 75 dex hurts weapon skillup speeds

But does being under 75 wis/int hurt mana pools? These alts are going to be sparsely played and wont get to 50+ any time soon and the mana may matter.
