Regions

Play Rate

Plot

The Gini Index is a measure of heterogeneity so, in this case and in simpler terms, how much the play rates are similar. The Index goes (when normalized like here) \(in\) [0,1] and it’s equal to 1 when there’s a single value with 100% play rate or 0 when all play rates are equal. Of course a Gini Index of 1 needs to be avoided but it’s not like the aim should be 0. As said, it’s just to add some additional tools.

Play Rate by number of Cards

Note : currently all dual region cards have only their main region as possible value assigned. It’ll be fixed in time for the next report but currently it makes so that BandleCity playrate is overestimated. The same problem also apply to the card’s inclusion rates, with Lulu being the most notable case affected by this.

Match Ups

Note : While these are indeed the Match-Ups win-rates that one can extract from last week games I need to point out that this is not the most accurate estimation you can get from my data. If you want a better picture of the current meta it would be better to look at the MU-page where I use all games with the current sets of buffs and nerfs. While it’s that there I don’t account for optimization and difference in skills acquired during the weeks the overall number of games / sample size makes them a much safer source of information. While I’ll continue to release the weekly data, pls refer to the MU - page for a better “meta-investigation”.

Match-up Grid

The win rates on the grid are among the 15 most played champion combination.

Match-up Table

Deck Structure of the week

Usually I don’t take a meta-deck for this section, but the underdog decks are either “old decks” or with just too few games. Next weeks I’ll more for some “hidden gem”.

Lulu / Poppy (BC/DE)

How to read the table:
- Play rate: How often a card is included in this class of decks / the table is order by this column.
- 3/2/1 is the relative and absolute frequency of the number of copies in the decks that plays them
- Frequencies from 50% to 100% are colored from shades of green to white to identify more easily the highest values

LoR-Meta Index (LMI)

The LMI 3 is an Index I developed to measure the performance of decks in the metagame. For those who are familiar with basic statistical concept I wrote a document to explain the theory behind it: , it’s very similar to vicioussyndicate (vS) Meta Score from their data reaper report. The score of each deck is not just their “strength”, it takes in consideration both play rates and win rates that’s why I prefer to say it measure the “performance”. The values range from 0 to 100 and the higher the value, the higher is the performance.

  1. Reminding that while I may collect the ‘list of all games-id’ played in a certain timeframe I can only collect all their metadata several hours later. So after the first release the numbers may be updated later during the week, be it for the sake of updating or modifying some code.↩︎

  2. Min number of games 50, during the times a meta/ladder just changed.↩︎
