Imagine a cowboy duel between capable shooters for example. Whoever draws his weapon first wins. You can have a 0.01 second difference and that character would win 100% of the time and the opponent can do nothing. Yet nobody would call that a stomp.
Essentially, matching what is on the
spite thread page, something is a stomp if one character is vastly more powerful than the other. That a character wins 100% of the time (well, more like 99% here considering that lucky shots exist) shouldn't be the sole criteria.
