Team Kill Efficiency
This stat measures the average number of objectives a team takes per kill, where an objective is a Tower, Dragon, Baron Nashor, or Inhibitor.

In-depth Conditional Win Rates
I will explore the win rates associated with some very specific game scenarios. For example, how often does a team win when taking the first Dragon in the first five minutes of the game? What are the win rates in 4-minute Tower trades for the teams that kill Bot vs. Top Tower? What are the win rates for players with Flash on D vs Flash on F? Win rates would be provided overall and separately by NA and EU LCS, LCK, and LMS.

Capitalization on Baron buffs
This stat would measure the average number of Towers + Inhibitors teams have been able to take during the 3-minute window after taking a Baron kill. Note: I only have this data for NA and EU LCS at this point, but will have it for other leagues in the future.

Vision control is a huge part of competitive League of Legends. We can measure teams’ level of vision control by looking at both how many wards they purchase and place, and how many of their opponents’ wards they clear out.

The statistics below are from the 18-game 2015 Spring split. Tiebreaker games are not included.

Points of Interest:

Warding Volume: Team 8 and Gravity placed the most wards, both in total and per minute.

Free Wards: More than three-quarters (77%) of Gravity’s wards were placed for “free” (that is, they came from a trinket or a Sightstone). Compare to TSM, Cloud9, and Coast, all of whom placed 63% or less of their wards for free. This suggests that perhaps the junglers on those teams are less likely to buy a Sightstone, which has certainly been true for C9 Meteos in recent weeks.

Ward Clears: CLG, Cloud9, and Team 8 clear the most wards per minute. All three teams cleared out almost 40% of their opponents’ wards, on average.

Opponent Warding Volume: Team Solo Mid is in the bottom three for proportion of enemy’s wards cleared, but is fourth in wards cleared per minute. This is because teams place a very high number of wards when playing against TSM: in fact, TSM is second for average Opponent wards placed per minute (CLG is first). In effect, TSM and CLG seem to instill a lot of fear in their opponents, leading to greater gold investment in vision.
