i think they need to have more character for this mode than mka they only had like 5 character. they need to have more and also, maybe more things you can do,

like scorpian for his spear, well instead of just pull people and taking there place, they can also climb walls or make it to go thought walls and they can have their own special abillty in a race, and can have fire ball or something to add more to the race , and more to there special that other can do because character will have there own move to do.
