Actually, figuring how J4's kit is, in theory he can be a really good support. His (Q) gives apen a decent range an best of all, unlike alot of skillshots it goes thru minions, his (W) shield is a nice aoe slow and because its a double lane its shield proc is higher then his normal, his (E) gives a nice armor and atk speed buff as well as being able to harass and poke and also combed with his Q makes for a nicve double knock up, lastly his (R) can single out and prevent escaping targets basically securing a kill, especially figuring your normally supporting a Range AD carry. So ya in Theory he is a very good support candidate.
