I love the Battlemage archetype, and being that this is an old RE, I'd love to see it get a revamp. Maybe this is too strong, but I thought it was a cool idea at having that warrior mage fantasy. It can be played 2h, DW, or sword and board as you just build your warrior abilities and augment them with the magic, and in my eyes would make for a great RE to play with
Battlemage: Warrior abilities have a 100% chance to proc your chosen mage subclass's main damaging ability (Frostbolt, Fireball, or Arcane Blast) at 20% increased effectiveness at no mana cost, and each cast of an ability will give you a stack of Battlemage. 5 stacks will allow you to instantly cast Pyroblast, Frostfire Bolt, or an Arcane Missle channel at -50% channel time, all at 20% increased damage. These spells can proc their respective spec associated procs such as Hot Streak, Fingers of Frost, or Arcane Missiles. In addition to this, you learn Mage Imbues, which there are 3. Fire Blade coats your weapon in fire changing your physical damage to fire, and has a chance of proccing Blazing Barrier, or lowering the target's resistance to fire by 50. Frost Blade coats your weapon in ice, changing your physical damage to frost, and has a chance of proccing Ice Barrier, or lowering the target's resistance to cold by 50. Arcane Blade coats your weapon in arcane energies, changing your physical damage to arcane, and has a chance of proccing Temporal Barrier, or lowering the target's resistance to arcane by 50.
