Inting Sion: Thoughts on how to stop or nerf?

As of recently the "inting sion" strat has begun to get traction. I'm seeing this more and more in my games, and it is every bit depressing and tilting. Especially given that sion is already a tough laner to face regularly. His w passive gives him immense health, and not to mention the shield that counters almost any trade. His q is ridiculously easy to hit if sion has already hit the slow with his e, and it does massive damage. And even when he is being beat he can still safely collect farm with his q and e range. But when he begins to solely focus on destroying your turrets, it gets even worse, granted that sion's team has at least one winning lane. When sion focuses on the turret, the enemy team must give up the turret, expand all their resources to kill sion and stop damage on the turrets, or kill sion but give at least a 1/4 to 1/3 of the turret health away for it. After going through 10 lives, it's easy for sion to have made it already to the inhibitor, or even nexus turrets. There's no real way to stop him. Others split pushing champions like nasus, jax, or tryndamere are strong, but not on the level that sion is. It's easy to make these champs run away since they can't take so much of a beating. They either don't have the health, damage, or armor to destory turrets like sion, who has enough health, armor, and damage to fully tank turret shots and enemy team damage, and still get a sizable amount of damage off.

It's a very easy strat to run. Posts are being made of hard stuck low silver players carrying this strat all the way to gold. I bet if their sion is taken away, they will lose. I know it's a simple solution to "just ban sion", but this is more than a champion counter. Int sion works in almost any lane and is extremely effective. There was a problem with laners being able to split push too fast with banner of command, and we say that get removed from the game. Obviously riot doesn't intend for champions to be able to split push as fast and efficiently.

I'm not sure what needs to be done to fix this (balance team's job), I'm just trying to find ways to beat it, or make it known to riot.
