WBSS stands for Wynncraft Balanced Skill Scale. It is a system designed to give a single 'score' based on your game stats, allowing you to compare with other players.
WBSS1 is the first incarnation, WBSS2 the later one. More info is at the following forum threads:
Keep in mind that WBSS2 isn't yet finished and I'm still trying to balance it, if you want a feeling of experience with the game you can trust WBSS1. If you want a feeling of skill or efficiency, you could try WBSS2 but I wouldn't trust it too much yet ;)
