It is very much "like" mana of other games... such as the one this avatar is from...whether it "is" or "is not" mana, is not a debate that i'd enter into.... however the Rate of these various types of points seems... strange, you use a lot more Administrative points than you do Diplo, and More of either one than you actually use of Military...
I can't speak for Wiz, but I find it a tedious meme as well.
Combine that with the fact that more than 90% of posts talking about mana are not in any way constructive criticism about the game, and I tend to just ignore posts that talk about mana instead of MP.
