I play in North America. Just about half of my ranked matches put me on foreign servers where my ping reaches almost 200ms. I still find matches instantly, so it isn’t even trying to keep me on NA servers. The only time it should throw us on servers outside of our region if it we are searching for a game for 5+ minutes.
This is the ONE thing that instantly kills my drive to play Halo for the night. Tighten the requirements to keep us in the region we play in. The best thing is to let us choose if we want to play in different regions at all.
