Tradeable vs Untradeable

In sets. If a player is trading in..as an example 4 83 players to to receive an 84 player. If in the trade 4 tradeable cards are used. The 84 card should be tradeable. If the 84 card is obtained by either untradeable cards. Or combination of both. It should remain untradeable. As it stands now. By trading in cards that are tradeable. That player is trading in value and receiving non value in return, regarding tradeable cards. Total ripoff. The same way they claim back goalie masks when you trade away a goalie. If the mask was purchased. It is the property of the buyer. Not for EA to reclaim.
