I've gathered some relevant cool down times from Destiny 1 and the Destint 2 Beta. This data was gathered from Voidwalker Warlocks from both games. [b]Destiny 1[/b] Max intellect super: 4:00 Max discipline grenade: 25 seconds Max strength melee: 25 seconds Min intellect super: 5:30 Min discipline grenade: 1:00 Min strength melee: 1:00 These times were gathered from the ingame menu. [b]Destiny 2 Beta[/b] Destiny 2 removes the old int/dis/str system for flat cool down times. These times were hand gathered by me and have a margin of error of about one second. Super: 7:30 Grenade 1:22 Melee: 1:22 Healing rift: 1:22 [b]Analysis[/b] The Destiny 2 Beta has cooldowns that are longer than the longest cooldowns in Destiny 1 by a significant margin. But wether this is a problem is up for debate.
