It doesn't segregate anyone. it places you where there are more people playing in your prime time than otherwise, allowing you to play the game to the highest degree each night.

Insomnia? really? That's a strawman argument. Regional servers are imo the best way to organize servers to get the most out of your playtime. That doesn't mean someone from EU can't play on a EST server, it's merely a label, a guideline, to allow players to gravitate to where they will see the most action in their timezone. That is all it is, do not blow it up larger than that by throwing around words like segregation.
