Jungler's Problems

Make sure jungle items can kill jungle monsters! 1 health issue - Jungle items like Hunter's medallion sometimes kill jungle monsters, sometimes don't. It's whenever it feels like it

Do not allow DPS abilities to kill jungle monsters except jungle items! Laners steal your buffs - If you have Twitch or Darius on your team their DOT abilities will steal your buff. This will put the Jungler behind as they get no gold or Exp and lose both health and mana in the process as result being unable to gank anymore

Give gold and Experience to Junglers despite who take the buff (the Jungler or his Ally) No Gold or EXP when giving buff to ally. So you are about to reach level 6 but you need one more camp to reach it so instead giving it to yourself you should give it to your mid laner instead just because Twisted Fate fails to use blue card to manage his Mana which can set your jungler behind
