there is not much rugby in Panama. Colombia had a team and coundlt maintained it, the argentine union ended paying for its second year, the last one before the end. It ended being a second argentine team. I dont think its the moment to add countries with barely any rugby. Only brazil makes sense, its a big market, and it has enough people to get a somewhat competitive team (still being last). As for the rest, stay with the ones with tradition in the southern cone, get chile and uruguay consistenly on T2 and the world cups, add more argie teams, maybe a second uruguayan and chilean on the mid future, and leave one in Paraguay and Brazil for a long time.
I dont think we'll gain much from adding a random lets say peruvian team, to get full of more argentine players, get more in Argentina were people go to the stadium and you can grow an audiance
