It absolutely does. The people on your server are who you play with. To this day I can remember dozens of people on my server that I'd randomly encounter in parties, and you knew who you were grouping with, and you avoided problematic people. If you needed someone for a quest you could search the lfg's and if you saw someone you knew, you'd ask them for help. And it was quite frequent you found someone you knew.

Stop westernizing ffxiv please.
