Just a suggestion about AL classes

[NiN]

Why do rogues use Mana Potions?
Rogues Should have 1 int.
It will be very cool if Rogues use a yellow bar = Energy. And we start with a full energy bar that goes down quickly while in combat but also regenerates fast when not in combat.
Warriors a red bar and have rage. Should start with 0 Rage but the more agro the the warrior gets the faster his rage bar goes up.
Mana for mages is just fine.

This way all classes should be balanced because the mage will heal more, warrior will tank more and rogue should focus on dps.
