Oh I'd like to add some very important things about playing overseas, that you may or may not have overlooked which make gameplay also Suck Ass:
If you plan on joining a real guild, plan on playing overnight. Timezone means you're going to be expected to start raids at 5 or 6am for EST guilds 8-9am for PST guilds. If you have a job in China, Good Luck.
If you want to find groups, being that the servers aren't so crowded, have fun finding groups with anything other than tired grinders or gold farmers. Everyone's sleeping my man, everyone's sleeping. Enjoy.
The whole reason this game is addicting..is the social aspect. There are probably more OZ's now, but keep in mind - of the "few" guilds that are on one of those servers, to get into it, you can't just rock up to level 60, be a good player, and join - there are server politics involved, and starting at the bottom anywhere that is well established sucks. That's why I server hopped and have 5 60s, on 5 servers, in USA realms: Blackrock (rog), Frostmourne (pal), Daggerspine (hunter), Medivh (druid), and a priest..I can't even remember at this moment where.
If you do have OZ friends in a killer guild it may be an option though
BTW the only reason I started a character on AoDeLanKe is because I was told there is hardcore gamers here and it would be a good place to start anew for an expat in CN, now I'm seeing like..not many online at all as you know and it's starting to feel like it will likely be another Bounce to 60 Others bounce somewhere else Quit the server and go somewhere new to try again type experience~
