One condition Final lap you have a timer to use your super (or something) so its not a shit show of everyone mashing supers at the finish line. Also have boss races. Atheon is a dirty cheater and teleports ahead and/or you back occasionally. Crota has a giant sword to keep you away from his sides. Skolas drops mine bombs behind. Oryx can take control of your sparrow on occasion. Could have low tier enemies occasionally swoop in like dregs on pikes, shrieker turrets, hydras jump ahead and race in reverse shooting at players, phallanxes blocking roads with shields, etc Pretty sure the redbull sparrow would be top tier with its bonus speed on top of tricks for potential infinite boost
