Jungle Kayle is fun, but I don't know how she'll do in the Season 3 jungle. They're making it harder, and so I think a lot of the less competitive junglers will go from being fun/situational picks to being completely unviable. On the other hand, Yi will probably do better in Season 3 jungle because the camps will be worth more gold than they are now.

Morgana is one of Semi's favorite mids, and probably the only support he'll ever play. He used to main Lux, so picking up Morgana was pretty natural to him. I'm not very fond of her though.
Here is a pretty nice video that explains how to properly use Morgana (also Gragas). The rest of the videos on his channel are really great too.
