Disappointed in Recent Title Releases... Is Blaz Blue Worth it?

Im buying this game from a freind to help him get money for his DS. Now im not really sure if I want to invest time competitively with this game or not. Hows the BALANCE with CS. Ive played this game I few times but never really got hardcore into it. I respect the balance in SSF4 and it has become a really important factor to me when choosing to invest time into fighting games. I also hear there is a CS2 coming out with further balancing like AE to street fighter. If I get into this game I will play hazama.
