I think the *can't-buy-players-from-original-country* is ridiculous. I do agree that you should not be able to purchase players from teams you own.
I agree. I know why they are doing it, but to penalize everyone for the actions of a few, is overkill.
Well, that is how the world works sadly. I'm against owning a gun, but there are some people who are fully capable to own and handle a gun, some others don't, hence a need for restrictions.
Which is an pretty inane analogy. You don't think that the end results of misusing a firearm are just a wee bit different from owning two teams and purchasing players from your original nation?
Another sim game - which has the same two team option in place - allows purchase of home-nation players (just no trading between teams), and has experienced little-to-no problems with the fears you express being realised.
