Why isn't Diana's Q being fixed?

Bugs, huh?

In all seriousness, I don't understand what you're getting at.

Q's bugs are pretty well known.

It's completely broken with smart cast. If you're not in range and you try to smart cast directly on top of a stationary champion, you'll move forward and throw it, but it will land short of where you targeted it and not hit.

Sometimes the 'explosion' at the end doesn't work. Even when it does work, the actual radius is shorter than targeted cast shows.

Sometimes if you cast it on top of yourself, it just plain does nothing.

It's extremely unreliable unless it hits someone in the arc at moderate range.
