I can't apply jungle pressure if.
You don't ward, don't look at your mini map, constantly push, and constantly feed kills to the enemy jungler. If you lose 1v1, i'm not going to gank you because we won't win, if you lose 2v2 i'm not going to gank you because we won't win. If you lose because of any of the above reasons YOU are what's stopping me from ganking, i'm not doing it for shits and giggles, i literally can't.
And if your a laner and you do these things then wonder why lee sin is camping you? MAYBE YOU SHOULDN"T DO THOSE THINGS!
I'm usually a laner, i don't like to jungle, THIS IS WHY! When i play jungle my team pushes their lanes in as deep as possible, then spam pings "Missing" on me continually when it's not my fault they pushed in and didn't ward, or if they did ward they don't know how to read a map. In addition, i'm not counterganking for a lane that's continually losing, if YOU keep getting ganked cause your pushed up and dying for it, you should probably learn the first time not to do it again. Not flame your jungler for not ganking you, it's not their fault, its YOURS.
-Sincerely, mid autofilled to jungle, flamed for 20 minutes straight.
Edit: Before i get flamed, ITS COMPLETELY DIFFERENT IF YOUR BEING PUSHED IN BY THE ENEMY AND YOUR NOT GETTING JUNGLE PRESSURE, BUT IF YOUR PUSHING IN AND COMPLAIN ABOUT 0 JUNGLE PRESSURE IT"S BECAUSE YOU WON"T LET THEM APPLY ANY!
