Wards as potential gold generating items?
What if wards gave their owners 1-2 gold every time they spotted a champ? But only if the champ was not visible prior to moving into the ward's range? There is some room left in the utility mastery skill tree, so this ability would be a nice fit below Scavenger (though this is up for debate concerning mastery balance). Or maybe a more expensive ward? I'm not sure if this concept would be overpowered or not, or if it could be exploited somehow :/
It would be a nice opportunity to boost the better junglers/supports that ward frequently and over a large area.
