People who are giving all credit to enma, I agree Emma is a powerup.
However if you have played NFS 2012 ,bugatti & lamborghini are very hard to control due to being very high speed cars. However if you can control those high speed cars you become a better player with minimal crashes.
So not everyone in NFS wins through high speed cars because they cannot control it. A Great player prefers high speed cars.
In the same way a swordsman needs control to be more effective & powerful.
I hope this clears confusion.
