I've used shatterdive in the past and it makes me feel like I'm not even improving as a player if all I need to do is jump into the air and slam down on the ground in close proximity of an enemy to defeat them in the crucible. Since then, I don't use the aspect at all... it's not balanced at all if there's literally no cooldown on it. For those who want it explaining in a simpler light: Shatterdive is as balanced as Telesto is good at staying out of trouble.
