I based his ultimate's cooldown on Taliyah's ultimate, given her ultimate is utility-only and terrain-altering. There's not much other precedent. Bard's is only one-way and disables people in the tunnel; this ability is two-way and you can fight in the corridor. Maybe the cooldown is too long. Or the duration too short.
