Please god no.The Only class who is capable of using Fel/Shadow/Fire/Arcane , and which uses weapons is Demon Hunter...
I know you dont see Demon Hunters as healers , but every class which uses Shadow , Fel (Nether, Chaos etc) , Fire can heal. Demon Hunters do use these energies and giving them a healing spec would add something new to the game.
Giving Different stances to DHs like Monks/Warriors/Druid would be something good.
I have thought about something special about DH healing...
Something Special about DH DPS.
But still cant find something special about DH Tanking.
Soon ill post the whole idea...
Its too long. The tanking side is based on Parrying and on Healing. Healing from The Fel/Flame Abilities. Still i need to think about something for DH DPS like low range teleports(6 yards , 7 yards etc) , low range charges , Shadow Copies ,Movement Speed , Low Healing ;Damage Reduces; a class which is based more on mobility than on High Damage Dealing.
