Just throwing some support out from an NA player, getting them servers (and south American) seems like it would be best for all partys. I'm not racist by any means and I dont stereo type based on where people where born.
This would give them lower ping and enhance there enjoyment of the game a TON, finally be able to do the ali combo for example!
This would also help the NA servers, far less 200-300+ pings in games. It really takes away from the skill the player truly has.
Kinda be sad to lose the great players from these regions though, but excited to see them at full potential.
