Unpopular opinion
Leashing is overrated. I had 20 games in a row with no jungle ganks after I didn't get any jungler ganks. To my surprise when I no longer leashed for them I was allowed to get level 2 before the enemy laners. Not only that, but normally getting enemy minions under tower made them miss a few cs. To top it of I saw a localized increase in winrate. I was hard stuck plat 4 for a few days, and bam now I'm plat 3 after I stop leashing. Games don't seem to be any more difficult or easier because I still get the same number ganks.
Idk I'm pretty sure I'ma get downvoted, but I'll test it out and get back to you guys.
