Azir's ultimate is still broken (worse than before)

In a bad way. I've seen it fail so many times now, in more than one way.

1. It will fail to push someone back.
2. It will fail to push someone back and deal no damage.
3. It will do #2 and not go on CD afterwards... Or atleast it looks like it wasn't' on CD, I didn't want to waste ult to find out.
4. It will fail to stop an enemy from walking through it.
5. Speed buff.. Is it there? This one I'm not sure about it, I've never really noticed it.

Fix this champion please.... And while you're at it, does Azir really need to stop to use Q? It feels really weird, Azir needs to be flowing, feel means a lot to this champion.

1. Fix Ult.
2. Maybe make Q able to cast while moving.
3. Show some radius for how close Azir needs to be to AA with his soldiers.
