Thanks for the replies all, as i said , i haven't experienced any lag, and am hoping that when i get into the harder raids it doesn't change, I don't want to give up my house on JP DC for reduced ping if i really dont have to.
I guess i could make a alt on OCE to test it out first, but regardless it will be hard to tell if ill get a house there, and its going to be a long wait to find out.
My FC is also moving to OCE but still leaving the original FC on JP, where i also have a nice room set up, and a apartment.
