This is why I went in on the Goku banner. I had more dupes to earn in Vegeta's, but having Transforming and SSJ3 Vegeta rainbowed scared me away.
Good thing, too. I pulled 3 Transforming Gokus and 1 FPSSJ4. rainbowed the former and 69% the latter.
That would have been 4 dead units on Vegeta's banner.
