For sure, but sorry, probably i forget something, but i don't see the negative in it.
If he plays smart, it's an interesting opponent. Should be a good thing, isn't it? Or you like to be promoted/win just because you have no opponent?
If he plays wrong/as a farm.... Nothing change. Or not?
I have to disagree with you on this matter, I know I would simply hate to play in league with someone from USA or China(once again I randomly picked two nations which have a lot of users/supporters), and I believe I am not only one who thinks like this... We have nothing in common, different language, different lifestyle, different interests, and even different time when we play bb... I probably wouldnt quit bb because of that, or something like that, but my in game enjoyment will be less...
I think this is a "storical" or "linked to tradition" motivation, and it can be understood but...let me answer in this simply way.
you're probably playing with a pc, no? He's done from companies with nothing in common with you. As you told.
And you're also using an OS. you can set your language, but also this is done by different people.
Ok, i'm joking.
Really, Different language but you've not to speak with him (or at least, isn't too necessary). And, don't know where you live, but there are "enclaves" of people from others nation in every single nation of the world, don't think this will be a problem.
Different lifestyle isn't so important in BB... also me and another italian user have different.. same like interests.
Different time is a problem solved because BB is active 24/7, so still don't know where is the problem. I play BB in a different time still from every italian user.
