Although the “competition” may seem fierce at times, I would not use the term “battle.” Getting into the top 20 is all about having the trust of the community members, not about fighting against others. Usually, this is done through positive actions like work for Hive, commitment, reliability, ... which do not seem to be the prerogative of a battle.
You are right, I just wanted to bring some gamification also to the witnesses space. I will think maybe to a better naming for the witnesses status, which I intend to track it on a monthly basis.
