Has riot acknowledged the low voice on project yi?

Hey Omega T33mo!

We have acknowledged it. ^-^

We're in the process of seeing what we can do to raise the volume. Since it's a legendary skin, there's a bit more to it than just moving a slider. We're hoping to have this completed soon, but it's certainly on our radar!

Hey again!

Just wanted to pop in and give you an update. We think we have a fix for this - we're in the process of verifying. ^-^
