So, you hated the old cross get system and thought it sucked. So did we!
So Majin thought this baby up a while ago and we release it to you know:
The Friendship System
Using this system will be much more realistic and fun, since you can do more than just mindlessly grind battle numbers to get crosses and other fun goodies.
If you need help, as in the 'Everything you ever wanted to know' thread, and someone will answer your question.
