Aurelion Sol Ult Idea

I don't have any specific numbers as to what I believe the damage or AP/AD scaling ratios should be, but I have what I believe to be a decent idea for what Aurelion Sol's ultimate ability could be. I think it should be a global ult where you teleport yourself to an area (very similar to TF's or Pantheon's ult) and grant vision in an area around you while dealing some AoE damage. The ult would probably need a fairly long channel time and a warning that Aurelion Sol was coming, but I think this could work as a good way to create map pressure and reveal sneaky assassins looking for freelo kills.
