Morgana Supports

Hello again.

I've been playing her as support and have been having quite a goo experience. I recently swapped from maxing her Q first as before I would max W. I also skipped making items like Solari and Frozen Heart after I have completed Zhonya. Instead I'm going for AP items like Death Cap and Lilandry.

Runes and masteries are as such, I'm looking for improve my Morgana gameplay in hopes of rising in ranks. Tips and any techniques more experienced Morgana players have would be awesome.
