There will be other ways to speed up your movement in Lobby available to non-backers. However, these backer shoes look really cool and have a trail.
I will update the description to be more clear - it is not for the Game Worlds or Dueling. The speed up only applies to Lobby.
Speaking of dueling, we haven’t completely shown that off or advertised it yet because we’re still working on that aspect of the game. There will be dueling in Tower Unite.
