Common ward spots map.
Vision is incredibly important in League. If you are the support then it is your job to protect your ADC and that includes protecting them against Rengars that might jump out of brushes. The team who wards more commonly, efficiently and effectively are usually the ones who win because you can't see opponents in the jungle unless you ward within it. There might be an ambush waiting there for your whole team and you wouldn't know. Junglers that are coming to gank will be spotted. Objectives in the jungle and river (dragon, Baron, blue buffs) might be being taken and you could steal it, etc.
Over time you will notice patterns in how the junglers and generally, everyone else walks around the Rift and you can use that to your advantage when it comes to vision control.
If you you buy a
(last forever until killed) at the start of the match and place it in the brushes that no one in the enemy usually walks into, it will last really long. These brush spots are:
•The brushes in between the mid lane outer turret tower and the blue buff (for both sides of the map). No one walks through there early, the jungler is too busy trying to clear so he wants the quickest and most efficient path and that's not the right way.
•The two single patch of circular brushes in the rivers are also good pink ward spots. Its coverage is really wide.
•The tri-brush between bot lane outer turret (blue side) and dragon and the tri-brush between top lane (red side) outer turret and Baron Nashor are good spots to ward depending on which side of the map you are in. The blue team usually has easy control over the tri-brush near bot lane so the blue team should pink ward it. For the red team to reach that spot they would need to overextend, it's more unsafe for the red team to contest vision.
After buying a
you should sell the
that you bought at the start of the match and buy a
to destroy any wards that the enemy might have.
is also useful for Teemo shrooms and Shaco boxes and those are always good to take down.
