General Discussion20-30 obs wards on the map, what?

What is this vision I don't get it, there is no treant in the game.

its an overlay you baboon

anti-streamsniping map

random guess would be that its a protection against stream snipers that overlaps normal map and fakes all the default observer wards that exist generally, but frankly speaking i got no clue how it could work technically

Y it seems like overlay in some way, but it's funny lol
