Can we talk about squishy junglers hurting the team?

I see tons of people picking squishy backline jungles like and ultimately sabotaging the game.

I had a game where the ADC did 75k and Mid did 57k, vastly out damaging the enemies 40k, but we still lost due to no front line.

Squishy jungles struggle to defend objectives and to lead engages. Without a way to engage the game becomes one sided.

The squishy jg's team just farms near base to remain safe, while the other inevitably more balanced team gets their pick at obj's and map control
