Noct's ult needs to be seriously nerfed, it actually lasts for the entire duration of team fights

I'm trying to play Ziggs, but Noct presses R and either my entire team is dead before I regain vision because I'm whiffing bombs in the general direction of the fight that I can't see, or I'm assassinated by literally anything walking up on top of me, and not being able to disengage it before it's too close because I can't see it.

This ability should not exist, in general, but at the very least the buffs to duration need to be reverted.
