The only way you could realistically and still make profit would be to buy the players 4 per and do it on a few accounts each challenge . You blow your profits if you have to buy the players for everything , I had half of them already and it still cost me almost 60 k just to do Clowney . If you have the time and know what you ' re doing it would work but def need to do it on a few acts each time . You ' re looking at a few days solid work between the AH times , xferring players and doing the challenges . That ' s assuming you get EVERY challenge in a couple tries , I had a 90 ovr team and had to restart a few over 25 times ! That ' s like an hour spent on one solo . Just not worth it for 240 k coins imho . Hope that helps .
