I have created this discussion from my own curiosity. This thread is NOT a discussion on what determines a tier, but what a tier is? The OU tier is determined by some percentage of usage. Any Pokemon found to overwhelm this tier and decentralize it is moved to the Uber tier. Similarly, the UU tier is also determined by some percentage of usage beneath the OU tier. And similarly, the BL tier is formed from Pokemon that overwhelm and decentralize the UU tier. And the NU tier is formed through the same principle beneath the UU tier. Now, looking at the LC and NFE tiers, they do not follow accordingly to the same principles that determine the Uber, OU, BL, UU, and NU tiers. Similarly to the other tiers, LC and NFE use Pokemon with Standard rules. These are only certain characteristics in common. But, do not follow the exact principle that the Uber, OU, BL, UU, and NU tiers follow. So are the LC and NFE tiers considered to be tiers? That is the question. The definition of a "tier" is a "rank or class." We can see Uber, OU, BL, UU, and NU tiers being ranked through a certain principle. While LC and NFE do not follow these principles. But, the definition of a "class" is "a set, collection, group, or configuration containing members regarded as having certain attributes or traits in common; a kind or category." Lets emphasize on "certain" here. All tiers have a certain trait in which they all use Pokemon and follow Standard rules, does this mean you can correlate all of them as tiers? If not, then LC and NFE tiers would NOT be considered tiers. But, lets look at it another way. LC and NFE can be tiers, in which they do not follow the same general rules of Uber, OU, BL, UU, and NU tiers. They can be a seperate tier of themselves in no correlation towards Uber, OU, BL, UU, and NU tiers. But, LC and NFE tiers have no common principle that they follow with another tier. Can we consider a tier that only follows its own rules without any classification of another tier to be a "tier"?
