Hey I got a question. I am in need of a ground, fire, rock,and electric support character. I want to know out of all of these which ones is the better BP unit so I can use my BP vouchers to get some support for those types. I have 3 vouchers to use and would like a second option on the subject before I go get them and if I should only get one unit 3 times or 3 out of the 4 supports.
