I didn't split push too much that game because my team would get solo'd by Mordekaiser. We won due to other team being stupid and getting caught out a ton, then we all pushed hard down mid each time, taking a little more of their base. We were stupid and stayed too long each time in their base too, then they would push down mid and we would have to defend. On the 3rd try of this back-n-forth we wiped them in our base and were able to get down fast enough to take their nexus.
I was able to 1-shot that twitch a couple key fights.
