I'm not having the same experience. On KRO, you can see the performer hitting 3 times with the skill in a 1-second spam, but on Muh, I can currently only use 2 skills. I'm not sure what the correct cooldown (CD) number is based on all the updates, but I'm definitely not having the same experience. Perhaps there is something on my end that needs attention, though I doubt it's a lag issue.
