Character: Elezen; Why? I find it easier to connect with an elf-like race (I rolled a Blood Elf in WoW and most MMOs I tend to pick elves over humans (not that I have anything against humans in MMOs, I just like a race that can specialize in magic and can, in turn, be self-sufficient.
City State:Most likely Ul'Dah. Why? Because it will most likely be one of the most populated, even if, by some strange circumstance, there are a lot of little kids playing in that city-state. Plus the more people there are in a place, the more likely I am to run into people who are nice, helpful and won't mind partying with me through Eorzea. Beyond that, the reason why I picked these two has more to do with the fact that I want to be able to make more friends with people, and the off-chance that I might finally find a guild I can truly feel acquainted with, without having to jump through fifty or more hoops. That alone is why I picked Ul'Dah over the rest, even if the majority of people there might pick races like the Humans, it just means I can complement people's parties all the better (even if I get stuck being the healer or the mage, I won't mind as I would be in a group that will work together efficiently).
