Why do mages not benefit from life or mana steal?
Any game i have played that has had life or mana steal has always allowed mages to benefit from it.
What is the reasoning behind not letting us benefit from life/mana steal?

Because this is a different game.

Because mages are supposed to be weak characters that have the highest damage attacks, it would end up healing to fast and they would end out invincible. I have never seen any game that allows them to use life/mana steal from their spells.

Diablo II for starters, can you name a game that has lifesteal passive that do not work with mages (besides DS)

Enjoy your whamburger and side order of french cries. Mages alreayd are fine why give them something that is not needed? Besides health drain is useless because a 2% drain does not keep your health up and mana drain on a mage seems to be a bit overpowered.

Are we talking about life/mana steal from melee attack on mages or something, because you couldnt mana/health steal from mage spells in diablo 2. I should know I played the game for like 3 years.

Haha I like that, lemee give it a try...

'Go call for your whambulance...'

Anyway, if you put points into endurance as well as intelligence, you could have a pretty meaty mage. Also focus on equipment that boosts int and end and you have a proper mage shield that requires no such effect such as mana or life tap...

ROFLOL.
I'm a Paladin with 7% health and 6% mana steal, I only use maybe 10 pots at at 30 min stretch Warriors are overpowered with it with the right equipment, give it to the mages... if the choose to solo like fools... give it to them. Your a "nuker" not a tank duh, and you can spam mana & HP pots duh!!!!!!!!
