@Likaizam If you're talking about the mining base urgent quest, the rankings are not based on damage.
The only means of testing damage in the NA version is the Rockbear training quest, which doesn't have the newest update from the JP version (JP version has options for a Rockbear that doesn't attack, just stays standing, which is great for testing damage. The NA version doesn't have that yet).
But either way, as nice as a parser is for self improvement, it's a bummer that people abused it and used it for harassing others in the JP version (which led to bans, naturally).
