Fast Points, Fast Exp!
First of all, all you have to do is play Delta Battle Mode over and over... Some of you may not like it, but you get a lot of Points usually 300 - 600 points per game ( If u and ur team are good ). About 300 - 700 exp per game. Also to add to this try getting a Bonus Combo Pack it helps alot! Push the THANK BUTTON!!! THANK ME!!!
