This tier comprised "god" tiered characters which have the innate ability to be placed onto any team, with any comp, and carry alone. Only a handful of gods have ever reached SS.
Your quintessential top tiers, which will generally dictate meta stylings and composition. These gods are usually first pick / first ban material.
Slightly above the point balance, this pool of gods should comprise the team compositions for most competitive games. The ebb and flow of meta swing and flavors of the month may sway this slightly in favor of certain players' abilities and strengths.
The focal point of balance. These gods should see no changes, given their current abilities in competitive high level play. New players should flock to this pool, as their time invested will likely not be wasted due to nerfs, buffs or changes to the playstyle.
Still somewhat strong, but not competitively viable in all situations. Are generally a bit more difficult to place on a team than A or S tiered gods. High player skill with individuals in this pool is likely to still sway a match up in your favor, but there are generally better picks.
Weak, overall. The team composition generally will need to be built around a character in this pool to make them work properly. Unlikely to be found in competitive environments, unless the player is considered a master of a god.
Very low pick rate and or competitively non-viable even in the hands of masters.
