Patch 5.18 Alpha Strike hitting stealthed targets, janna ult stunning, sona E [ARAM]

Currently for me if Janna ults you into a wall in Aram you are sunned for a short while. (Assassin skin) Yii alpha strike hitting shaco while stealthed without fail in Aram.

Sona E aura affecting enemy Kog'maw while it is dead (greatly increased move speed once you enter her aura).

The janna ult thing has been since 5.17 and the Yii alpha strike is new experience.
