First go for the 10 Pickup tournaments. That will get you the Pickup tournament pro achievement. Then go for 10 cash tournaments, that will get you the cash tournament pro achievement. After those 2 are gained, simply play 5 ranked exhibition matches, and youll get the ranked tracer achievement. Easy!
Though it will take you a while to get the pickup and cash tournaments, as they are annoyingly long. each pickup tournament is 6 matches, and cash tournaments are 10 matches. so that is a total of 160 matches. I got it, after playing for about 5 hours per day for 2 days straight, boosting with a friend. You wont find people online unless your boosting, so find sum1. Just not me.
