j4 and vi is my go to pick whenever im autofilled jg, theyre mega strong in any patch tbh, they could tank whilst dealing tons of dmg. idk how riot always manage to forget to nerf these champs. shyvanna vid when boss rebs hehe
J4 is mid tier at best... so many other jg's who outperform in almost every aspect. Mao, Viego, Vi, etc. If you are looking for someone tanky and has a lot of utility, sure but you are essentially a glorified support. Can be good for some but not for most.
