[Unanswered]  Should my Kerbecs' performance tip wear out?

Is the metal fight performance tip defensive spike (DS) supposed to wear out and become a more flat performance tip, making my beyblade more aggressive? So, I've been playing around with my new bey, Hell Kerbecs, and recently, my bey has become a lot more aggressive, and when I checked the bey out, the spike part of the performance tip was off center, and it was hard getting it back in the middle of the defensive ring. Also, the defensive ring is starting to touch the floor more, so in conclusion, should defensive spike wear out?
