Jungle tracking
Junglers have typically two options
3 camps into gank vs fullclear (6 camps) into gank
Reason for this is first 3 camps gets you lvl3 and the next 3 gets you lvl4, and for junglers cycling camps is the most important.
Value wasting enemy junglers time
Junglers will continue clearing in the order of their first clear aka if they started top to bot they will continue doing that for rest of the game and vice versa for bot to top.
Look at your own junglers position to evaluate plays when youre unsure of enemy jungler.
