A hero with ability to reduce visibility for enemy team

[sausageskin]

Imagine a hero with an Ult ability that reduces visibility for enemy team for several seconds. This could be implemented as a thick fog, in which enemy players can only see within a couple meters, while team mates can still see normally (like Nocturne in League of Legends). In addition, enemy players will not be able to see the map for the same duration of "darkness".

This is what Hazes ult should be rather than Reapers "die, die, die". Makes more sense for the character imo
