Question about Inting Sion.

last game we were super behind and had really fed enemy lanes. However, we started picking up the pace and actually started towards balancing the game out and in certain team fights even winning or gaining a lead....

BUT NOPE INTING FUCKING SION. The enemy Sion just kept throwing himself at the base, we'd kill him but nope his retarded passive would kick in and sometimes he wouldn't be able to do anyting with it, other times he would take an objective regardless of how much pressure we put on him. And this is mainly due to Demolish and how it works so well with his passive health gain and the fact that even when he's dead he can still proc demolish and pummel a turret down.

I'm not saying that Sion's numbers or kit needs a direct nerf because frankly it doesn't. What needs to be changed however is his interaction with turrets. Hit ult smashing into turrets for a quarter of their health, demolish taking out a fuck offing massive chunk and being able to persist on a turret even when he's killed is such a toxic mechanic that it works in all elos from Silver past Diamond.

The biggest issue that arises from all of these things put together is how it forces your team to respond to it. He's essentially shorting his team a member by focusing on your base and in response you have to send at least 2 people or more if you lack a significant amount of CC to attempt to stop it. Which puts you at an overall numbers disadvantage comparatively.

Sorry I forgot the question. How do you play against this? Especially if your team is any kind of behind.
