because basically in total to rank up a player to level 30 you at least need maybe 2,150 rankup points/tokens to fully upgrade the player.
level 10-100 rankup tokens
level 15- 220 rankup tokens
level 20-450 rankup tokens
level 25-560 rankup tokens
level 30-700 rankup tokens
so in total its 2,030 rankup tokens to upgrade a player to full rank which is level 30 to use the player to its full potential, and lets be honest most people will not be able to do that. It will take them how long to accumulate these rankup tokens before they can upgrade the player to its max. So please EA make it more easier so we can as well transfer rankups to players as well like you did with training players introducing training transfer points. Thank you.
