How so? If played right you can get it so that you are between your target and his team and knock him back into your team and get him ganked while the other team is slowed trying to get to them. The horse have it better for that situation and it tends to be way more useful. If you play ally Ele sham you can do that yes, but you are just knocking them back to their own team enabling them to be healed full and what not.
