Thank you for your feedback! A while back, the prototype concept for Bak Mei involved giving him 3-second cooldowns on his abilities, but at the time he was also more of a bruiser/juggernaut than a melee carry, and so I figured making his abilities essentially empowered basic attacks, and making each instance of utility/CC extremely short-lived, would make him run more smoothly (by contrast, a per-target cooldown would make more sense for on-demand, longer-duration CC, imo). His ult is really powerful on its own, but I think that's justified, considering it's literally the only source of ability-based damage he has on his kit, and requires a huge amount of setup to land. He'd likely be able to use it multiple times in a fight, but at the same time you also have champions like, or  who could all deal potentially a lot more damage within that same duration (Fiora especially could potentially deal a lot more max health true damage, even without her ult).
