===Barbarian===

In the first publically shown build of [[Diablo III]], shown at [[WWI 2008]], the [[Barbarian]] used [[mana]] instead of [[Fury]]. The [[D3 Team]] never actually intended the Barbarian to use mana and the first build only used it as a placeholder. The second version at [[BlizzCon 2008]] used a fury globe, much like the World of WarCraft rage, but this was changed shortly after the event to the system we see today. The [[BlizzCon 2009]] build used the Fury Orb system, where fury builds up to "orbs" (where the mana container is for [[caster]]s) and some skills require 1-3 orbs to use.

===Monk===

The Monk will not use [[mana]] but a martial-arts related resource pool.[http://diablo.incgamers.com/blog/comments/monk-resource-system-complete/] No details have been released, but a system similar to the [[World of WarCraft]] ''Rogue'' character seems likely.

===Witch Doctor===

===Unannounced Class===

Since the class is not announced yet, we can only guess if it will use [[mana]] or some unique resource pool. Considering [[Blizzard Entertainment|Blizzard]] has talked a lot about unique resource pools, it's likely he or she will get it's own system, or perhaps 4 different systems is enough. We'll have to wait and see.
