Sightstone gives increased exp for killing wards

So I was excited that Riot added exp for killing wards but since that happened I noticed I really don't get that much exp from it since when ever i find a ward someone usually takes it before me. So what if gave either the exp or an increased amount? Edit My friend came up with a better idea gives exp when you ward, but to prevent other positions from abusing that it only gives exp for the first 3 wards, wards that replace wards don't, UNLESS you clear a ward first.
