Most online games have Dedicated servers that everyone connects to, and that parses out information.
The need to worry your connection to an every changing host is ZERO in games like Battlefield, or Destiny, or WoW, or Daoc, or Eq2, or Guild wars, or Wildstar, or EVE, or Elder Scrolls, or Final Fantasy, or Team Fortress, or Mechwarrior Online, or.... Do I really need to continue?
You know this, stop being silly.
