You can have for example jackal mount having the same running speed and same dodges, but maybe add different skills, maybe instead of maul you add a support skill when you dismount, mounts help you to move around the map and makes the game more interesting, with the warclaw arrow you can easily dismount someone if you do it right, but having only one mount for me its too simple. You can definitely add new things that will make the game more fun. I like the fact that warclaw has some skills that you can use in wvw. Add jackal as a support mount.
