Playing against Sion
How to counter and exploit weaknesses
His Q charge can be interrupted by CC — stun him during the channel to cancel the knockup.
Sidestep his R (charge): he can't turn easily once he's started.
His zombie passive is slow: simply walk away from him, don't stay in range.
The W shield can be popped before it detonates: burst it quickly to prevent the damage from going off.
