The chain storm has to be used specifically in such a way that allows you to hit everyone, it works most of the time but then sometimes it just doesn't
"The reason why chain storm is better is because of the range. It has smaller range than jade rain" Also it never matters how short your cooldown is aslong as ur trying to sync it with ur leg spell even a 4 sec cd is the same as 6 sec cd just cause of leg spell
