Volatile dead + spell cascade interaction

as the title said interaction is really weird and Spell Cascade is a must have if you want to play volatile dead.
Spell cascade doesn't auto target other corpse it creates a weird alignment in a line and if there is no corpse in this line it doesn't create other volatile.
So it's pretty unplayable cause you need to aim in a special way but you don't even where you need to aim because the animation of spell cascade appear after you cast so 90% of the time spell cascade hit no other corpse.
