Overpowered champs are very strong in this current meta that recently got direct or in-direct buffs or those that overshine everyone else. Stat-checker champs can also appear here. You would want to play one of these champs.
S - STRONG
Strong champs are still very strong in this meta but don't quite fit S+ Tier. They might got buffs recently and are still stronger than other champs in this role. These are also champs who we think are sleeper champs that haven't been discovered yet.
A - AVERAGE
Average champs are OK to play, are strong but on par with other champs in this role. Sometimes they win lane and sometimes lose but overall good enough champs to play.
B - BELOW AVERAGE
These champions are weaker than a lot of the other champions seen in this position. Generally, these champions will struggle to carry or take over games. Champions who are reliant on specific champions being played in the meta can be found here when they are out of relevance, alongside champions who have been given repeated rounds of large nerfs.
C - SUB-OPTIMAL / NICHE
These champions are those who have been typically nerfed considerably in the past, or who are not normally seen in this position. Often these picks are used as counter picks or as a player's main champion that they continue to play despite their potential weaknesses/limitations. These picks are not recommended unless you have experience with the champion in the past.
