not ganking a lane because "scared of double kill"
This has been so many cases in my game where I'm stuck in a losing matchup and my jungler doesn't wanna gank because of they are scared of a double kill. I understand if the guy is 2 or 3 levels above the laner, and is one shotting the dude, but when they are only one level behind, and actually able to damage the champ, gank their lane. It's that simple. It's like if 95% of the people I queue with just have no idea how to jungle.
