To be honest, the only problems I have with our summoners south-of-the-border are the trolls. I think the problem is there are a large group that give the entire group a bad reputation. It may be this same issue that leads me to say that also play style from summoners south-of -the-border generally sucks, lol. But again, that could just be because the squeaking gear gets the attention, I know it's not everybody. And there are trolls from every demographic, so no we just can't pin this on one group. HOWEVER, it does seem like more often than not that its this same group that will type in spanish, portuguese , whatever, and then complain about the team not working together.......and thats when I go "really, you think? herp a derp".
What I would really like to see is the option to choose what "demographics" you want to play with. If you only want to play with English speaking players, you should be able to check a box and go. If you don't care, but really hate people from Papa New Guinea, you could check every box but them (what do they speak btw? lol, I don't have Papa New Guinea's either btw.) But you get the idea. Will trolls still troll? Yes, but it would be a nice start, and its not like games don't insta-pop now anyway. I donno, I could be wrong there, just an observation.
End of the day, it is an issue and its giving some players a bad rep. Easiest thing to do know is to just ignore the trolls when they start typing. I think have a theory that the best way to piss off an 11 year old Brazilian kid trolling is to just ignore them.
It's not everyone, and in general the summoner population has become really mean in every way imaginable lately, a huge change from when I started playing. Instead of encouragement and constructive criticism, its nothing but hate and rage. This is, yes, the fate of any game that becomes popular I agree, but it still sucks .
