As someone who has both a NA and EU friends, having EU/NA data central travel will make this game finally perfect for me.
I still mainly play on EU for having proper ping reasons. but i yearn for being able to play with my NA friends on my main account, since they are useally playing it more then my eu friends. I do have a NA alt, but over a long time it really becomes bothersome to keep leveling that up as well. especially since most of my jobs are leveld on my main and I have glamour/mounts and everything set up.
