The junglers job is to use their time the best way the can to win the game, either it is spent ganking, clearing camps counter jungling getting deep vision, rallying to take dragon, Harold. It is advantageus to gank lanes but there is risk and time investment. there is a chance they will get nothing out of it or worst case scenario they get counter ganked and the enemy laner gets 2 kills setting the you further behind.
as a jungler i am more likely to gank lanes that ward ping them MIA's, enemy summoners, and do not have early deaths. do these things and it makes your lane more gankable and more apealing for a jungler to gank. spam pinging to gank your lane will get my attention for like 5 seconds but if it continues you will get muted and I am sure that is common for many junglers.
As a Lane you need to understand that every jungler wants to win just like you do and they all have differant ideas of how to win the game depending on their particular matchup the information they have on the map, the opportunities they see (within their skill range of course nobody is perfect). A jungler wants to get ahead in farm just like laners do and by ganking we are not farming (though we do sometimes tax to keep up or get ahead). some junglers want more kills to carry the game, others try to give the kills to laners if they think they can carry or win lane.
Did you know that laners can gank jungle? if you are pushed up and see a fight in the river or in the jungle if the enemy or your jungle invades you can gank. you can gank for the jungle and secure a kill. you can get vision in the enemy jungle to help the jungle with their pathing by providing more information as well. laners can gank other lanes. if you notice they you are going to lose lane and the jungler is active on the other side of the map followup with a TP play and get that first tower blood( this takes practice and experience). There are is more but this should get ya started
The purpose of this is not to bash you or any other laner but to add prospective to what you can do to help your jungler even when he cant or wont help you. I understand there are bad junglers but a great laner can make up for that :) help us to help you :)
let me know if there is anything i left out or if this was helpful
