Mariner's Vengeance interaction with Zilean's Ultimate is stupid

I was playing the new aram and makes ultimate useless. ability procs before ultimate so if you're you can never ultimate that person if the item passive is up because you wasted your ult because the person doesn't revive because the item assumes they died already upon taking fatal damage.

Riot please this is stupid... If everyone on your team had it you could never ult anyone on your team. Potentially the worst champion in aram with only 3 usable abilities.
