I disagree with nearly every point.
If it's easy to get kills with, why is that, up to March 31st, you only have
twenty kills with it across competitive and arena?
I don't know how the coolness factor about a weapon makes it overpowered, so I'll skip that.
I think your point about placing the grenade in a specific place to get a kill and by "douche-E" I assume you mean players are being cheap when they do this is a flawed point for the weapon being overpowered. Because the grenade bounces, it's very hard to place it on the ground where you want it to be. And, frankly, it takes a lot of patience to wait around for the opportune time patience not many players have. As a result, not too many of the gun's kills are a result of this tactic. I'd be surprised if you had more than ten deaths, out of 119 according to Bnet, as a result of this course of action.
