Fighting games are imbalanced. With both characters being played optimally, one character will always have either an advantage or disadvantage over another character (with the exception of mirror matches, of course). Understanding matchups will not only help you make better-informed decisions on how to defeat certain characters, but it will also help you mitigate your own disadvantages. This guide does not lay out a specific character-versus-character matchups rating table, as these are incredibly fluid over time and anything whipped up a month before release will almost certainly be outdated quickly, but it does mention glaring weaknesses that you can exploit in certain matchups.
