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.
The past part is how you get a jungle pool of only a handful of champs and a meta of only 3 of them. Not to mention it makes it so much harder to balance champions that could flex between jungle and other roles.
Is buffing dmg to camps a somewhat arbitrary and forceful way of approaching jungle champ viability? Yes. But it also makes it a lot easier to balance.
