Would be neat if there was a grand arena, kind of like how ancient romans raced chariots. I noticed with my dragon that if I jump while running that I speed up a bit and can overtake and pass a dragon and others of the same speed who are not likewise jumping. I want to race my purple dragon in a full size grand arena, and it would be neat if different mounts had different powers or if we could cast spells at each other while racing. and we could power those up or get special mount gears through the typical ticket winning system.
I think a mount race track in the pet area would be a great idea. My friends and I like to race our mounts where ever we can find room to do it. Since I bought the life house, we have found a nice ledge on the top, where racing out mounts works well, but would like a track better.
