This is the first of probably many such topics. Since the Dev Team is in the process of considerable overhauls, I think we should remove some features that add more complications than gameplay.
All ideas presented here have already been discussed very shortly within the Dev Team and we found no obvious reasons why we should keep that particular feature. However, we ask for feedback from all players for a reason: If it turns out that the feature is beloved by the players, we may keep it for that reason.
I'd like to remove buying regions. It is never played as intended (i.e. most players don't accept it as a legitimate title), and I don't think it really adds all that much to gameplay. I do believe that it can be replaced by something better, in the future. And for the moment, I don't think many will miss it all that much.
