Saw a funny Chinese comment so I translate it here.

Junglers in the Past:

I have small AoE skills with a short cooldown to take camps quickly so I’m a jungler.

I have quick movement ability to traverse the map so I’m a jungler.

I have great gank setup/damage potential so I’m a jungler.

​

Junglers now:

My abilities deals 300% damage to camps and I can Q smite at 2000 and one shot dragon so I’m a jungler.
