@Sp3w4567 So imagine this. Each player gets assigned a trade value. And in order to make a trade the the point values have to match.
Say like an 84 elite is worth 1000 trade points. But an 81 is only worth 300. And higher tier cards have a higher trade value.
So you couldn't trade a tier 1 81 for a tier 4 84, you would have to add more players to the trade to match the trade value of the player you want.
I'm sure that even this system could be exploitable, but it's something we all want and most guys would use it properly
Some type of trade system would make the game much more engaging and interesting.
