Aurelion Sol's Ultimate rework idea

Seeing how 's Ultimate is very lack luster, I suggest making his ultimate more of a channeled skill. Similar To how Zac's Jump expands on his channel, you should make Sol charge up his ability and have it instead being an instant cast laser, be a AoE Bombardment that moderately detonates stars starting from him, to the outer extent of his ult's range. Dealing higher damage to champions/minions closer to him and dealing less than 50% on the outer edge of the skill. This will give people time to run, but if you get slowed and run along the bombardment you get hit at most 3-5 times. This will give people the chance to run closer to sol prior to shooting off this ulty, or if they are too close and they done die, they can stand there and hit him till the rest of the skill finishes. Another cool bit that can be implemented is that if you his someone who has been stunned with your q, you get either a bonus damage on hit, or increase the length of the stun, so if someone wants to use a quick ult after landing a star, you can have enough time to kite the W around it. A cool way of letting this ultimate be used would be probably executed would be to have him exhale and the Area that gets covered in this dust like ability be subject to detonation, meaning the range would be clearly visible and have a bit more interaction with the ability.

To be honest this is more of an idea to make this quick boring shout laser into more of an engaging ability.
