Karma's Inspire (E) plus Jarvan's flag
I discovered today that it's actually possible to use Karma's shield (E) on Jarvan's flag, for whatever reason. While you can use her shield on minions, I feel like this is an oversight allowing her to shield Jarvan's flag, because why would you ever shield something that can't be damaged? The flag definitely should not be able to be targeted by Inspire.
While we're at it, would it be possible for her Inspire to prioritize champions over minions? There are few things more frustrating that trying to save a teammates life, only to have this ability hit a minion instead, and watch helplessly as your teammate dies because they were too close to the minion wave. Just my thoughts, though.
