It's not bad. You only take half damage while you're stunned and if they're too close it won't even stun you, it'll just bounce off. Originally it had no minimum range and full damage while stunned.
When I was struck, it was two Scouts gunning right towards me. Id estimate the stun time at about 5 seconds, which is more then enough time for a scout to wipe out a Medic. Hence why I didnt let them nick me with it again. Regardless, if I took no damage at all, im still extremely opposed to giving the strongest class in the game more tools against the class they have the biggest advantage against.
