User blog comment:Mineko Charat Lucky/Stop Telling Me What to Build, Thanks/@comment-24073036-20131020112539

I had an experience in relation to this post. I was playing as Twitch and my internet started having these bad lag spikes (PH internet sucks) which ended up with me feeding and my team dissing how bad I was (I'm not that good but having 1k ping cripples anyone). We were at a disadvantage and was being pushed to our base. I only had BotRK finished and noticed that the opposing team was bad at sieging even given our disadvantage. I opted to go for a split-pushing build and bought a Runaan's because having me at team-fights will just result in me lagging then getting killed.

I wasn't the focus of the enemy team because I had been feeding more than often during the game and wasn't much of a threat. I even got a lot of flak from my team for building that item and caused me to mute my entire team before they completely put me on tilt (I wouldn't recommend doing that but there are times where EVERYONE is being an ass). While they were defending the base 4v5 mid, I was being a pest and shoved the top and bottom lanes mostly uncontested. Fortunately, my team held up against their sieges and my split-pushing created enough space for us to regain an advantage. I eventually made it all the way to their base because they didn't send anyone to intercept me and our exposed nexus turrets we really appealing to them than a split-pushing feeder Twitch. They made a critical mistake and most of them died next to our turrets and I got to push all the way to their nexus while the rest of my team TP'd after me to bag the win.

tl;dr: item choices are not static. they are on a game-to-game basis. Experiment and see what works for the current situation!
