Save a life, buy a ward
I have noticed in many matches people are not warding. I look at the map constantly and it looks like I am the only one warding most of the time. I keep having matches where there are NO wards on the map from our team except mine. Then later on down the line a teammate will finally pick up ward and place it even though we are past 20 min in.
I dont know why people are not buying wards and if they are i dont know why they are not using them. You stop a lot of deaths by using wards but no one seems to understand that concept.
So please, when you guys play, buy wards and use them. And if you feel extra confident, go for the sightstone.
