Life Aura like Discipline would be great !

A lot of people in this thread are saying this aura, would be OP but it really isn't. +50 scaling up to +100 life is equal to the life of about one piece of gear, and this idea seems like it would mainly used for melee/attack builds that don't take any aura nodes. For those builds, you almost definitely didn't take any reservation nodes on the tree, in which case I would probably use one of these combos for auras:

-Hatred+Grace
-Hatred+Determination
-Hatred+Herald of Ash
-Hatred+1 Purity

Hatred is basically a necessity on a melee build, and for the second aura Grace, Determination, or the additional max res to cold or lightning from a purity will add much more to your defense than a life bonus equivalent to one piece of gear will, while Herald of Ash gives more damage.

its not anymore op than CI users using disc... I've been thinking about this for a while and I personally think it would be a good addition to the game considering how underpowered melee builds are and have been since beta.

60% mana for 100hp? no thnx

It would cause a ton of complications if you ran out of range and made someone lose a chunk of their hit points and potentially making him or her RIP because of it. If it were a herald type spell I could see it working, only works if it reserved mana though, because blood magic would cause a ton of complications again.

Too similar to Discipline. The devs generally avoid making skills and uniques which are too similar to one another, even if they are to parallel the function of another skill.

Case in point: Wrath/Anger/Hatred, Herald of Ice/Ash, Grace/Determination/Discipline, Molten Shell/Tempest Shield/Arctic Armor etc.

I feel like it would be hard to balance in a way that would make it a choice and not mandatory or junk. I think of discipline as part of the downside of ci, all the es values on gear and the tree are balanced around the fact that a ci character will be using it.
