Oh sweet, another one of these threads. We totally needed more.
Seriously guys - if you can't get on an NA/EU server character, play on a JP server. There's nothing to stop you from doing so. I tried for about 15 mins to get on my main today, no luck, spent a couple of hours getting my character on Kujata from Lv12 to Lv16 and completing a bunch of story quests on a different nation than my main. I started that character last weekend when I couldn't get on to Cactuar. I got to play because I used a little common sense. If you really want to play, you can.
