@Santoryu D Bazooka See one point while i'm rewatching the video is about Galaxy Impact and he's pondering on some bringing up that it could only be AdCoA and not AdCoC, if we take the trails out or not enough conclusive..
The answer for this is.. I would tell him that AdCoA needs some sort of medium to flow in or container..
Why Galaxy Impact is primarly AdCoC + AdCoA attack is because AdCoA can't flow in random air, it needs to be directed, thus why Galaxy Impact looks like a Big Balloon, AdCoC is not focused it just serves as a barrier to somewhat hold AdCoA..
And if you look at it, Galaxy Impact is just really AoE, it doesn't seem that much potent..
