I started playing on a japanese worlds yesterday and haven't had any problems, but I expect later I will if for no other reason than the time difference. She'll probably become my "I need to escape and go solo for awhile" character because during my prime time the server population is scarce.

The idea of just having all worlds listed so the population can sort itself works for me, except we can't sort ourselves since we can't tell what the load on any of the worlds is. I know companies don't like to list their population numbers these days, but even just a word or graphic designation for population level would help.
