Strength (y-axis) is based on how effective an item is in the situations where it is most used. Items that are strong at all stages of the game are listed higher.
Versatility (x-axis) is based on both the number of Compositions an item fits in and Champions an item is used on. Versatility is also how often you could build an item.
Compositions
Tiers are determined by what I think will get you the highest average rank. This means that while one composition might be super strong late game, it may be difficult to acquire, so it may not be S-Tier. For example, it is difficult to win with Berserkers, but extremely easy to Top 4, which makes them S-Tier. Rankings within a tier are very close together. Always try to play with what makes sense for every game, and adapt to your lobbies with proper tech choices.
Difficulty, Item Dependency, and Variance are listed. Difficulty is how hard the composition is to play. Difficulty does not factor into the strength or viability of the composition but serves as a factor for new players. Item dependency is how important specific items are to the composition. Variance is the approximate placement range of the composition. For example, a consistent Top 4 composition has low variance. A composition that either places 1st or 8th has a high variance. If I mention that a composition is Forcible, it means that you can play this comp every game.
Tier placement assumes strong play.
S-Tier: Highly Flexible or Very Strong
Ranger Warden
Difficulty: Medium
Item Dependency: High
Variance: High
Inferno Shadow or 6 Inferno – FORCIBLE
Difficulty: High
Item Dependency: Low
Variance: Low

Summoner Assassins
Difficulty: High
Item Dependency: High
Variance: Medium
Ocean Mages with Wardens
Difficulty: High
Item Dependency: Low
Variance: Low
Hyper Roll Predators
Difficulty: Low

Blademaster Mystic
Difficulty: Medium
Item Dependency: High​
Variance: Medium
Berserker Poison Desert – FORCIBLE
Difficulty: Low
Item Dependency: Medium

C-Tier: These are compositions that are weak, but if they are given to you, you might be forced to play them.
Meta is cool
Thanks for the YT Vid and these builds. Climbed from S4-G4 sampling stuff out, but mostly with the Berserker build. TY!
Nice job keeman! Berserkers are a little weaker this patch, but definitely playable if you get an early Olaf!
