So now that Oracle's elixir has been nerfed hard, we find ourselves unable to deny sight anywhere for more than 15 seconds and there's no cost effective way of having Oracle's power on hand when you need it.
I would like to see an item that gave you a short term Oracle's power as an item activate. Say, 15 seconds worth with a 90 sec cooldown. That way you could use it to counter stealth & wards when you need to without being able to wander around with Oracle's up all the time.
It might also be worth considering having the sightstones stack charges every N seconds rather than refreshing every back, which leads to the current situation of wards everywhere all the time.
An alternative to consider would be having every Nth wards produced by the ruby sightstone be a pink ward, but this would require charges to stack every N seconds, rather than every back, or it would get silly fast.
