At this point you should be making bombing runs every Ult cooldown and then jungling inbetween (Your Combo: Fly in, Maybe Vines, Ult Bomb, More Vines, Gargoyle Someone, Heavy Melee, FINISH THEM)
This build excels at team pressure and jungling. Thorns being the main focus of your damage and team fight support as well as the ability to make "bombing runs" from above with the ultimate.
