Sona bug or visual oddity.
In an ARAM. Our team's blitz hooked sona at full distance. Sona instead of being yanked to blitz just popped straight up. multiple people commented on it. Later I seen it happen again. It may have happened more times, but I was paying attention on two of them.
I asked her in the lobby how that works and she said it is due to her lag. Still wondering what that is about, seems useful and sure worked in her favor every time. Not sure if blitz ever successfully pulled sona that game despite landing them. Dunno if it was one time bug, an exploit or whatever else. Oh well I wasn't happy :(. Hard enough winning a game without consistent weird stuff happening. Just glad it doesn't happen often. First time I seen unusual spell activity that consistently benefited one player.
