What will your first character in Eorzea be and what nation-state will you start in? Why?
This is really difficult for me to answer, as my primary choice is not/will not be available at launch. So I'll answer twice.
I would start off as a Female Roegadyn from the Sea Wolves clan. Primarily using Pugilist, with Lancer and Archer Abilities. Square-Enix stated a few times that some abilities will work in tandem with each other and there is a set of abilities I really wish to test this out with. Quickstride + Tackle. They stated the distance you were from the monster would effect a Tackle's damage, But what about movement speed? Its interesting things like this that I wanna try out.
Female Roegadyn still seem to be a wish without a gift. So I've resigned myself to playing as a Miqo'te Keeper of the Sun. I'll probably still try similar things out with her, but instead I'll be mainclassing as Archer and using Lancer like abilities.
The nation state is easy.
My favorite Zone in FFXI was The Sanctuary of Zi'Tah. I love the music, the atmosphere, the attitude. As a result, I think I'll be most happy hanging out in Gridania. I'm not some tree hugger, It just seems like its going to be the most calm of the other cities. Less Traffic, Less annoyances, calmer attitude. I'm hoping to enjoy my stay there.
