If it is actually better, we will see it abused in high elo. No need to form a blood pact ;). But yeah man, jungle is like zero impact role, unless enemy midlaner INTs pre6.
I had a game yesterday, full cleared, killed enemy jungler. Ganked bot got two more kills. Full cleared top jungle, then went to clear my red (and botside spawning soon). Enemy midlaner is level 6 and I'm level 5 and I suspect he's at my red. Enemy jungler, level 4 0-1 gets to clear my botside jungle because I cant contest enemy midlaner. My midlaner is afk farming mid, spaming me with question mark pings and I am doing the same to him. I don't die, but game snowballs out of my control from here as they 4 man dive my botlane. jungle is literally zero impact, midlane is all that matters.
