Man, it's really funky how ARAM teams can sometimes end up being five immobile melee champs against five ranged poke mages. Meanwhile, my large support pool means I'm often stuck with them (Rakan's pretty cool in ARAM, though), and some champs such as Lulu are downright boring to play when you can get paired against too many bursty all-in champs for your W and R to handle.
Having copied the tear start from a Ziggs, I'd say it's a great item to get when you want to spam ranged poke the whole match without having to pay attention to your mana.
