Seriously. Why is it even an option to play in another region where you will likely get a worse ping, not speak their language and annoy the ever living ♥♥♥♥ out of the people there. Now I can understand competitive play allowing folks play in different regions where they may compete but now with the team system you're likely to play in a team and that could easily be excluded from a region lock.
Nothing is more frustrating than playing in US east or US west where, by pure localization, the spoken language is typically english. Yet more often than not you get people yammering in spanish, brazilian portuguese, russian, french, etc.
There is nothing good about this. How are we expected to play a team game where communication is basically not possible (the radial menu only goes so far)
