Does Volibear need a rework?

I tried messing with his build and it seems so weak and awkward. As a jungler your flip usually saves the enemy so I end up rushing glory for it's active and then using his q other than that he has a lack of CC if your laner can't catch on to your gank. yet you're not tanky enough to take be the main tank for your team. Your passive doesn't regen as much as mundo or singed. Feels like volibear could use a look at. what do you guys think?
