More importantly that would imply that the tmp is now shooting at the same rate as a pump shotgun. The percentage chance of a proc is per shot, and usually races that can easily oneshot kill someone, like a vagabond, have weapons restrictions. True a raiden or nebula can one shot if their ability procs, but in order for it to be a one shot it has to be a high powered weapon, like a pump, or a headshot already. Trying to "balance" them is not only not worth anyones time, but impractical and frankly, stupid.
