Pyromancer - classic ranged nuker who has a hard time not lighting themselves on fire if engaged in melee.  All spells should inflict friendly fire, but be very potent.

Demolitionist - Uses explosives such as bombs and 'powder packs' that can be hidden on the battlefield and detonated by bombing/shooting.  Can use a smoke bomb to create chaos or an escape route.

Botanist - Potions and plants are the botanist's specialties.  Can plant vile seeds that will quickly sprout from the ground into carnivorous plants which ambush enemies.  Can imbibe intoxicating brews that grant temporary strength or protection.  Can also throw noxious vials of spores which slowly but surely kill their opponents. 

Arcanist
A magic-user who focuses on the deeper secrets of the arcane arts rather than using the elements.  Less a direct damage powerhouse than the Pyromancer, the Arcanist utilizes a skillset that includes powerful control aspects, but relatively long casting times.  The following abilities are some examples:

Reality Distortion: The Arcanist disorients a single target from reality, randomly teleporting them once per 2 seconds for 6 seconds total.

Arcane Barrage:  Fires a salvo of perhaps a dozen bolts of magical energy that hit the first target they encounter.

Energy Burst: Knocks a nearby target far away, dealing moderate damage.

Distortion Mines: Forms several mines at the target location which explode when enemies come near.  Affected enemies are damaged and pulled to the mine's location.

Energy Barrier: Friendly fire possible.  Forms an impenetrable wall of energy around the target, making them immune to damage but unable to act for several seconds.



Enchanter
The Enchanter has the power to exert mind-control or boost allies' competence and courage with their mastery of the magics of illusion and enchantment.

Manifest Will: The Enchanter exerts their power over another, holding them in place and dealing damage while the skill is channeled (up to a maximum of a few seconds).

Dominate:  Wrests control of a summoned unit from its owner.  Permanently.  One dominated subject per Enchanter.

Mirror Image: Create several mirror images of the Enchanter.

Doubt: Causes an enemy to doubt themselves, their cause, everything.  They suffer large penalties to physical damage, mana regen and defensive stats for a short time.

Work's really slow today... so another idea:


The Imperial Deva
Kinda like the Engineer's battle-hardened grandma.  The Deva is one of the Empire's elite, ember-powered super soldiers.  She wades into combat encased in a suit of armor that's as much about offense as defense.  It's joints are powered by hydraulic pistons, the forearms are equipped with flamethrowers and two chain-gun turrets are mounted on the back.

Auto-Turrets: The Deva engages her armor-mounted chain-guns which spray bullets at nearby targets.  Long cooldown.

Fire Wash:  The Deva opens the floodgates on her flamethrowers, burning units in a close cone in front of her for as long as the skill is channeled.  Enemies are set aflame for a few seconds afterwards, too.  The flames knock enemies back slightly.

Power Thrust: The battle-suit's hydraulic legs allow the Deva to rocket forward a few meters, inflicting a stunning blow to the first unit hit.

Power Swing: Hydraulic pistons in the arms help deliver a powerful blow to all within striking distance.

The Gentleman

Dang. This is one of my uncles!
