Does Hextech Starbust need that AOE dmg? Suggestion for a change.

To be completely honest this item is good enough with just the dash... but that AOE dmg? And it is cheaper AND has a stronger effect than Hextech GLP-07A that has lower ratio and base dmg. I know that to use the dmg you have to put yourself in danger but it offers too much defensive ability to be this strong. So here is my suggestion - Remove the AOE but give it a burst of flames or something behind your champion as they dash away (like a fire from a jetpack)
