This logic is incredibly flawed.
If "Tanya, Shinnok, Quan Chi, Kung Lao, Liu Kang, D'Vorah, Kotal, Jax, Johnny, Predator, Erron" are all either overrated, not Top 5 or both as has been stated by main's of the characters, then who is the real Top 5? Is the real Top 5 Sonya, Kung Jin, Kitana, Sub-zero, and Takeda?
What seems more likely? Massive downplaying, or that people don't know the real Top 5? Or is it one of those things where whoever is speaking about a Top Tier main being not Top 5 is correct, but then they list the same Top Tiers everyone else does when it isn't their main?
