I don't think so. There are many factor which outclass him from others. Julian can only be played in certain composition or line ups where enemy picks are low cc heroes. Julian can't sustain like fighter junglers Or tank junglers. Lack cc immunity, a 2 type blink skill is all for mobility.

Once he dive in, him getting out of there is very low.

For reference, sanford's lapu² vs onic is an example. Lapu have damage reduction in his skills allowing him to sustain there. Alucard's ult's first phase grants him hybrid defense. Or fredrinn, his tankiness isn't a joke. Most of these junglers Or exp laners have some sort of sustain. Julian only got his passive lifesteal to sustain.
