How does a player become 'in-form'? By using him in FUT or is that an attribute that is static and given to the player from the get-go?
Also, it seems like selling players rarely nets the value I would expect. For example, I bought a rare silver pack for 3750 (i think thats the number, im at work right now) and only got 3 actual players and none were rare. The kits/badges and training stuff doesn't seem to net more than 150 coins, if any. With that in mind, you'd have to get about 750 per player to make up the value. Seems like coins are best spent on auctions since you can dictate position etc and get someone who really matches your squad
