Let me stop you before you emberass yourself, if you’re willing to listen
Jungle main here, gold elo currently, and i love playing proactive jungles like Vi, Kayn, Rammus, and now a smidge of Rek’sai since shes just that op right now
If a jungle does not like a champion pick specifically, theres usually only two major reasons:
Either the champion puts the burden of the entire gank on the jungler, like a soraka top or other champs with no engage or hard CC
OR
The jungler isnt well versed in seeing the champion played (ganking for a strange off-meta pick like singed ADC or Azir top) so much so that they’d rather not risk
Alternatively, the ENEMY laner may be an obscure and high threat pick like a Rek’sai top or a really hard to catch champ like an Ezreal or Tristana
If you harrass your jungler with flame or pingspams, they may well decide you’re not going to be cooperative or may become a liability, so theyd go onto plan B, which coincidentally i will now talk about replying to the next part;
Now on to your second made-up gripe, and what it means to the jungler that you may be missing:
A losing lane will often be dropped because of strategic reasons. Tell me which sounds like the better choice here, one lane is HARD losing. Two lanes are doing average.
Would you rather spend the entire game trying to dig the player, who already proved they are less skilled than their lane opponent, and let the enemy jungler ruin your other 2 lanes into a loss and thus win a game with 4 or 5 full power enemies versus MAYBE two if the jng successfully gets the top fed
Or alternatively, push all the influence into winning the other 2 lanes, then outnumbering the one LARGE threat 4-to-1?
Its much more likely for 4 full strength winning champs to beat one, than two kind-of-okay strength players against a whole team of fed players.
Good junglers dont ignore winnable lanes. They want to win as much as everyone else. If someone seems like a liability to the game, or that helping would be a way to lose the lead the jungler has, they will. Every decision is a calculated risk, and ideally the least likely to fail. You gotta reflect and ask if that liability is you, if this is frequent.
Heres an idea to understand why we do what we do:
Look up some guides on pathing and ganking.
Try playing jungle for a week and cater to people the way they want you to, and then play the way i described, ignoring losing lanes and snowballing good lanes to outnumber the lost lane. If you do it right, there’s only a couple hypercarry champs that can 1v5 a team with 4 fed players. Thats a small handfull out of like 160 champs, and some (like Yasuo) will usually be banned by one side or the other.
Those are good odds
Alternatively, ask some jungles about why they do what they do when it comes to deciding which lanes to ignore or camp, and if you ask nicely they’ll usually be more than happy to respond. See how many give you the response I’ve given
