# THE META REPORT NAME IS TOO LONG, TOO DAMN LONG (n°36)

Patch 2.21 - Week 1 - Ionia don’t be broken challenge: Impossible

# Data

Note: With the current Season I want to start using a “more robust” way for which games to collect. Reason being that while I want to focus on Master players it’s possible to notice the flaw that

• Once a player reached Master he/she stops playing so it’s equal to be non-existent for the analysis

• As of now, without an incentive to climb the Master leaderboard is less populated and yet it’s not like all those lowers are probably that much worse. I noticed for example that the data from the Master of the previous Season still had very similar results regarding win rates. But using the “last-Season” masters is also quite an unstable way to pick the players/games.

So the proposed solution is the following:

• Collect Master Data as usual

• Collect games from HighDiamond players. With “HighDiamond defined as those who played against a Master but aren’t”. Of course if a Diamond reaches Master I stop collecting his/her games as Diamond but start as Master. This may also help to create some analysis based on “skills”

• For the early weeks of a Season I’m going to collect the games from those who played the Seasonal tournament (of course this is assuming it’s held each season which is a safe approach I guess). If I should show all the results or either LastSeasonal/Diamond or Master/Diamond is something I still have to decide. Adding more stuff can be fine but the report is already big like this.

Number of (Ranked) matches analysed 3277 or 6554 games. / LastSeasonal Players

Number of (Ranked) matches analysed 23335 or 46670 games. / ~HighDiamond

2 Metadata from Friendly Matches (that aren't Bo3) is not recoverable, the value may not be perfect since I lack the starting time of the game. The amount of Games to still scrap is also an estimation based on the 'position' of the game

3 n(%) took from the number of matches. When the data is analysed the size is double since we account each different player

# 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.

# Match Ups

Note:: only games from Last-Season Master

Regarding MU, 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 dedicated MU-page where I use all “Ranked” games with the current sets of buffs and nerfs. While one may object I don’t account for optimizations and differences in skills acquired during the weeks, the overall number of games / sample size makes them a better source of information. So, in case, please refer to the MU - page for a better “meta-investigation”.

## Match-up Grid

The win rates on the grid are among the 10 most played champion combination. The upper value is from all the Last-Season Masters, the bottom one only from the current Current Masters. MU with less than 30 games are not included.

# Deck of the week

## Ezreal/Kennen (IO/PZ)

I actually wanted to feature something else but, after recent events maybe the deck even needs “some help”

## Deckcodes

- 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)

• Tier0 with LMI >= 97.5

• Tier1 with LMI $$\in$$ [85,97.5)

• Tier2 with LMI $$\in$$ [60,85)

• Tier3 or lower with LMI < 60

The LMI 2 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.

## Interactive Version

Top3 Players (or more in case of ties) from each server that had the highest amount of consecutive wins with the same archetype. The provided deckcode is the one played in the last win found.

# Credits

Special thanks to bA1ance and Pavelicii for the recent support ^^ 4

I may not express gratitude often but that’s because I think the best way I can do it is to continuing working hard on what I do and strive for improvements. Still, proper credits are necessary and I’ll try do it to them more often.
