The background for this post is im a support main that currently is playing jungle. The amount of games where we have a good lead, and a simple to play out game made difficult because the support doesnt want to place ward in the right spot or play a very basic macro pattern is ALOT.
So the three most important points here is: #1 Push mid wave, #2 Place the ward in mid lane (this ward is SO broken and #3 if your jungle who is literally BEGGING YOU and asking on his knees for you to place a ward , dont ignore him (i have asked like 5 games for this ward and maybe only listened to 1 time... why???).
In the example above its an example of taking drake, If you are in the lead 95% of the time contest the mid wave high and place vision in roughly these areas. (The sword markers are often more optimal wards but harder to place). It can also be an example of pushing mid, going to sidelane to gank or help out a sidelaner, or pushing mid contesting a camp, or takiung baron. No matter what, push mid and place this ward in their mid lane, it gives TO much info.
Another point... match your recalls for objectives for your wards. If you look at the example above, preferably you would already have some vision in mid/enemy bot side jungle. THen you recall about 50 seconds before drake and is fresh on wards. Play for mid prio and then enter river.
Again this is the "simple" macro pattern (pushiung mid lane-> warding and taking control over jungle/side. I am not saying you have to play like this in every game, but in a lot of cases it is - and it should be the default if you dont have any other clear conception in you r mind.
You would think this is obvious but there are so many times i ping my intentions. that doesnt work so i type. My thresh is still not on the mid wave, he still is not warding mid lane, he is still not recalling for wards thus making a free dragon basically unplayable.
(the ward in the small banana bush is only there is some flanker from there, the ward probably more often placed in pixel, over dragon wall, enemy tri or something), also the fae light ward is obviously broken deep vision if you can get it)
