Reaper is meant to be a fast, mobile, in-and-out character. He's made for skirmishes and 1v1 duels, as well as sustained hit-and-run attacks. Like in Starcraft II, he's meant to have a lot of self healing to keep him on the battlefield. While his self healing may seem a bit out of control, and his Aggressive Stimulant may seem a bit overpowered, Reaper would have an incredibly small HP pool (Maybe around Nova level - maybe even less) and would be very susceptible to burst damage and crowd control. He would also have a reduced attack range, like Tychus, forcing him to get up close and personal with enemies. Reaper would be good at locking down a target and sticking to it, with his mobility and brief stuns, but good teamwork would require a Reaper player to chose his battles carefully.

With this concept, I really tried to capture the aggressive nature of the Reaper. Supposedly, they have heightened aggression through chemicals or something, so I tried to represent that in his abilities. For example, with Aggressive Stimulant, he has to be chasing or attacking an enemy.
