Official Blizzard Quote:
Instability on the wizard
All we know is what Jay Wilson said
she gets more "Blasty" as she gets more "vulnerable"
They have said it will make more sense then mana did once we learn about it which is cool
This is no longer the case. More at BlizzCon.
We have gone from Mana, to instability, and now to something that may be entirely new. With this brief response, we are left to speculate on what "this is no longer the case" entails for the fate of instability. We do not know if this simply means the resource has been overhauled and no longer behaves as explained, or if the system has been scrapped entirely and replaced with something new.
In the event that instability has been replaced, we have no wonder, where else can they take the Wizard's resource? Of course they could have returned to the mana system, but with Blizzard's previous focus on providing a different resource for each class, I highly doubt this is the case. Perhaps the Wizard now has a system in which they gain a chance for spells to fail after several casts, or hell, maybe they've switched it so they gain mana from the life force of their slain enemies.
At any rate, we can all take solace in the fact that Bashiok has cleared up the remaining skill resources for us, with the exception of the fifth class, of course.
Official Blizzard Quote:
The barbarians fury system (Last we have seen) works like this
The barbarian has certain moves he can use
Hitting with these moves generates fury to do better moves
Some better moves take away fury balls
Last we have seen, He has 3 fury balls, some skills use one some use two and so on.
Kind of. No more fury balls.
Any damage the barbarian does or takes generates fury. This fury builds up as his resource, to a cap. When not doing or taking damage there's a grace period, and then the fury will begin to recede.
You build fury to use skills, as the majority of the barbarians skills require some amount of fury to use. There is a shout that generates fury itself, so it's not always necessary to be in combat for a while before you can start using skills.
On a side note, Bashiok also confirmed that the Witch Doctor is still using mana, and the Monk is still using a "holy" system that fits with his class. We can only wait and speculate on how this will be represented in game.
I hope they show ALOT on Blizzcon!
If not... I don't even know what I'm going to do.
But it'll involve alcohol.
I see what you did there.
on my part i cant wait till i finally get some news
