It's definitely been dominating for me in level 1:

Is fast trainers still a valid strategy?-image.jpg

My squad is worth like 15-17m and just about anyone I face has a value of 5-6m, in the cup I've seen someone with a value of 9 that was level 2.

BTW how would you guys do with the fast trainers season 2? Sell the current ones and buy new or keep riding them?
