Well for both characters I mentionned, it serves as a kind of gank initiation, where you know something bad is probably stealthed here, but you don't know who, maybe it's just the jungler, maybe it's also the mid who came to the party.

You could also use it in the middle of a fight to give some "untargetability" to your allies so they can avoid some damage, giving them time to maybe reposition or get out of the fight.

Or as an escape, because if the area is large enough, it might be hard to hit a skillshot on something you can't see (even if you know it's in the area).

It could also be used as a bluff tool, I mean until you get in their face, they have no clue how many people is there, so it could trick them into running away for the time being, buying some time for your team for whatever, or making them use an aoe initiation tool (like Amumu), which allow your team to safely get them from behind, knowing they won't have to fear that big ult, but you probably die for them in this case.
