Death Skating Game Mode

My idea for a rotating game mode that could maybe appear around Christmas. All players have at least 500 movement speed, or just a really fast amount and they can't stop moving once they leave base. It'd be like a fast paced version of summoners rift but the jungles have been replaced with Icy ponds. There could be buff items like in Nexus Siege or Poro King that give you abilities, like speed bursts or a grappling hook. Just a silly idea [slayer-pantheon-popcorn]
