Well, if I'm playing Poppy, for example, if I get a leash I do a lvl 2 gank on bot. If I don't, I lose the timing. The leashed jungler might also have prio over a non leashed jungler. Just don't see a reason to drop the leash, even if it's shorter.
This is so true. If I don’t get a leash, I just end up farming jg for longer to catch up, then there is no good gank bot, because my bot is pushed up
