While I agree that this gun does look sick (Totally have been wanting it since it got spoiled in alpha) I am not 100% certain it's over powered. No slide+shotgun attempts by his opponents, it does get beaten a few times at medium and long range when people actually shoot at the guy, and I barely saw any use of supers here. Just watched it again... most of the time people are not even shooting at him... I feel like this could have been accomplished with a Suros or a variety of other AutoRifles.
