If you're gonna go Smite TP top, USE THE DAMN THING.
You're taking those for Cinderhulk and map presence in teamfights and objectives. So use the damn things and get with your team once in a million years. Please. You're wasting Flash, the holy-fuckin'-grail of summoner spells just to take something absolutely useless for you.
Don't blindly thump the meta. Just 'cause the LCS does it doesn't mean it's unicorn-riding Jesus made of money and happiness.
