I can see why DIANA is so OP!

Diana is Bae.

I have some questions.

1. For my 3rd point, I always put a second point into my shield for shield reasons. After that, I max R>Q>W>E. Is there any reason you get e early? It doesn't do damage so I don't get it until later, lvl 5 maximum.
2. Why do you get chilling smite? What makes it superior to the other ones?
3. At 9:10, when you were doing scuttle, wouldn't using your E reduce it's defenses, making it easier to clear?
4. You could Q,R over walls to get to your camps faster. (Not a question, just a tip).
