do you not understand what missing smite does to a jungler? they don't get level 2 from the first camp. they have a secere gold and exp deficit all game. there is no objective control, something that affects everyone.
when a laner forgets their summs. it is embarrassing. when the jungler forgets their summ. it is a very large significant loss in win chance. and this is because riot is trying to balance the jungle, which means they are taking it upon themselves to care about this sort of thing. which means I get to ask them to fix it, since it got hurt within this past year.
and I never forget my summs. but I can't control when some random I'm paired up with does.
