I think we can all pretty much agree that to run out of mana in pvp these days, you must be doing something wrong.
In vanilla, casters used to run out of mana so fast. I remember constantly drinking on my mage.
Nowadays, the only way I can run out of mana is by spamming Spellsteal, Healers NEVER (Like really never.) run out of mana.
Sometimes kills we're made with wands (may god have their souls.) because of the lack of mana to cast a final spell.
I think that aspect of the game made it much more immersing and really made a mage feel like a mage.
Would you like to bring back mana management for casters and healers?
