Area's I tend to ward when I'm in lane in bot lane
The Buffs are really only necessary if you feel the need, but you'll want to have those warded if your jungler is having some trouble or if the enemy team is constantly taking your ***
in lane bushes are important in case of a lane gank
Wards i generally place while top lane
In lane wards top normally don't seem to be as important unless the enemy jungle starts to realize you're actually warding your river, then you may overextend and get lane ganked which can sometimes end up in a death
I'll normally ward my/the enemy teams red if i feel the need to
Sometimes as a jungle If i take another teams red that is topside i'll give it to my top, so i just have that fear in mind (it can *** your lane up bad)
Ward blue too if you really want to
The wards mid should all be easy to understand some being more aggressive than others
These are my normally placed wards as a jungler usually just because I love keeping tabs on an enemy jungle while I'm jungling
And I'm very controlling and like to take as many small camps and buffs as I can
That and some of the wards are to help with your lanes in case their ward wears off and what not
These are the wards I generally will place after whichever based is being pushed in, some give more control over certain areas than others
I forgot to include the wards over the walls of baron and dragon and the ward over redbuff's wall as well, but those should be included
The midlane wards are normally there to know where your enemy team is headed because lategame if the minion wave isn't there it becomes sort of a dead zone
