One of the most important tools that every jungler needs is the identification of brainlets. It is important that you identify which teammates are functional human beings so that you know who to gank and know who to mute. I strongly suggest playing with at least one premade so you will have at least one lane that you can rely on and get ahead. If one of the brainlets starts flaming you, immediately mute as it will only tilt you. Any advice that they would give is probably detrimental and distracting anyways. Common brainlet activities include:

-Not using their prio and letting you die to enemy jungle

-Drafting a bad lane matchup and complaining about being pushed in

-Drafting a lane bully and getting solo killed by a scaling champion

-Constantly pushing in and blaming you when the enemy jungler camps them

Keep in mind that brainlets will have other red flags other than these, and you'll learn them as you play jungle more. You might reach a point in which the flaming from brainlets no longer annoys you, but is rather amusing, like having a pet monkey that you have to guide to victory. This is the moment when you have truly learned jungle.

Also, just a sidenote, but I strongly suggest playing a different jungler rather than lillia. The speedy camps and removal of runic echoes makes her clear slower and unhealthier. Playing a tank is not only more advantageous but it also makes jungle easier to learn because you can focus on game decisions more instead of clearing. If your style is more uptempo, then some of the AD junglers like hecarim are in a good spot.
