Pink Wards 101
First thing you want to know about the reworked pink wards, they last until someone successfully hits it 5 times. So a well-placed pink ward can last the whole game. If you stick them in your jungle and you manage to successfully let your team place 5 of them all in your jungle, then you’ve already reduced the number of counter jungling and potential tower dives your enemy can do.
In the attached picture, I put Pink Circles for the blue side of suggested ward placements for pinks. If you follow it, then the blue buff is directly warded and doubles as a warning for behind the tower dives, the red buff has no possible entrance where you can really go to without being spotted unless enemy placed a deep ward and TP’d to it. The top side river is also fairly warded and would probably last a long time until baron vision becomes a factor that same river ward also protects mid and top lane a fair amount. This also provides easy jungle collapses since you have vision control of your own jungle. Almost the same principle for the purple side denoted by the orange wards only there are more wards top lane because there aren’t really any good places to put them so supports should ward somewhere in the river but you still have that really strong pink ward near mid lane that tells you a lot of information and is easily protected by the mid lane and jungler. Next are the Yellow Wards those are neutral places to put pink wards but advisably just used with normal wards with the downside of not having true sight (You can still use Sweepers). These pinks should be placed only when your team is grouped and want to take objectives say a turret or dragon or baron. Lastly, the purple wards are sneaky little wards that no one really checks and still give you a substantial amount of information. Use this when the enemy jungler isn’t really a good counter jungler. Ohh and one really important part, PINK WARDS 100% REVEAL AN ENEMY CHAMPION BEFORE IT DIES, so, it’s never a waste.
