Can there be a bit more clarity with this passive, by which I mean his ability to upgrade his teammates items. I mean someone who's playing Ornn for the first time is going to have no idea how it works, no idea what items are upgrade-able, and no way to tell his teammates he needs to upgrade their items. You can't ping your passive so the only thing you can attempt to do is ping their items and hope they understand. Of course anyone who doesn't play Ornn won't understand, nor will they even notice when he does upgrade them as their is nothing signifying he did so. Not sure if this is being further updated for clarity but it feels really sloppy at the moment.
Quick edit: It would seem that despite allies only being able to have one masterwork item, it still tells you that they have items to upgrade
