yer good thinking with the points system being equal.
The problem with any trade system, even if it was fair and no cheating occured, is the impact on the current economic setup.
Lets think about it - You manage your team economy to pay staff and player salaries, pay for scouting, The profit you make is used to enhance your team - like building up you arena, buying more scouting points, buying better staff members, and - buying better players.
Once your arena is full size, and your only spending $10k a week on scouting points, what do you save ur money for?
Purchasing players! :)
So here in lies the problem - if you start trading players, what on earth do you do with all your spare cashola?
So thats the problem - the game economy is based on around excess money being used to purcahse new players, if you take that away, (even partially), then the whole game economics would need to change - drastically - which just can't happen.
Does that make sense?
