I need help with my earth main lineup. I currently have:

X X X

Sasori MC X

Sakura Guy X

This is my talent page:

These are all my ninja (I'll get Kakashi tomorrow since I started playing 5 days ago):

Also I don't buy gold so anything with buying for real money wouldn't help me.

I didn't see a lot of earth main topics on forum. Do you think I should change my class when I get to lvl 60 or leave it like that?
