I'd love to play this on IOS!
A class I???d like to see would be a nano-robotics expert. With the futuristic development and miniaturization to nano-scale tech, experts are trained to coordinate a swarm of imperceptible nano-drones as a delivery system for medical stimulants or deadly toxins. The mental strain, however, required to direct the simple machines would somewhat limit the nano-expert's ability to participate in combat.
The nano-expert would operate as a glass support that must be protected by a tough, combat-ready squad. Nano-experts can develop expertise in two diverging paths (often dictated by their morality or risk-aversion). The first path would focus on healing and buffing allies with medical stimulants and the precise medical attention. The alternate path would specialize in using the nano-bots as weapons to gain abilities to incapacitate or even manipulate enemies by invading and "hacking" a targets mind and/or body.
That would be awesome, right?
