While that may be true, again, if someone (us) were to use the tier list, it would do nothing for us. We don't know the full details of why characters are high tier or low tier enough to even use them for the reasons they are good, or know the reasons why characters are low tier and what counters them so bad that they ARE low tier. Basically to us, it doesn't help.
We know the true potential of the character at optimal skill level with full knowledge of the game, but we don't have the knowledge to make decisions to make the characters even perform at those levels.
Not to mention, there are tons of new characters that weren't in the arcades. Tier lists are done based on matchups, and which characters have the best matchups overall. Any one of the new characters could completely destroy the high tier characters, or the low tier characters could have good odds against the new characters.
