The video I shared is by a fellow Gurdian over on reddit. To my believe its been over 3 years now since (back then Top Tree) Dawnblade ultimate has had a small but infuriating bug introduced to it. With the back then introduced second icarus dash, that in neutral play has a 5 seconds cooldown, the Ultimate does normally not have this cooldown. But if you start clicking to rapidly to dodge fast back to back you still recive this cooldown, making you unable to icarus dash during your ult for 5 seconds, even tho it is not shown on the side of you screen, meaning that its either not intended to be there at all or that the Visual is missing.
