I think it would be beneficial to segregate by general location to cut down on the amount of delay or lag you experience in-game. It's been really bad lately and talking with some of the other USA and Canada players, most agree it just hasn't been fun.
The delay we experience in-game is unnatural but has been accepted here on Graal because it is beyond the players control(in most cases)
Not asking to completely segregate players by location or remove any of the existing rooms just to make that clear. Give the players the option though.
Also USA/Canada room pertains to me but other worldy rooms if they make sense could be beneficial as well.
