I can't believe no one else has ever wondered if horse (mount)) raceing could be incorporated.
I might have a fully trained mount, but I always see players with much fastrer mounts than mine - so some skill must be involved. In each, or just particular zones the could be a 'point to point' course, maybe a circuit of the zones extremities. A race might have 12 participants, each paying 1,000 gold to enter, winner takes all. A new way to break Activity Finder?
Saddle, Bridale and shoes could be a new craftable skil? Saddle Bridal Shoe sets give mount tempory ability like 'swim'
I obviously havn't thought this through.......
