The reason why devourer junglers are hard to balance

all of these champions does nothing but smash people in their face with AA, they do nothing other than that.
if the meta is good for them
, they become overpowered and does tones of dmg by just aa people at their face.
If the meta is not good for them, they dont do enough dmg and they cant kill people, which mean they become useless.
to make these champions easier to balance they really need some sort of rework to bring some utility into their kit, so they arent useless if they cant hit people hard enough.
