Hiya Rozien! And welcome to Eorzea! P.s. Vesper's guides are good!

In terms of interface, it won't flow as intuitively as Warcraft if you're using the mouse (I.e. can't right click on a vendor to sell, an item to equip, etc.) So it may take a little getting used to.

Gamepad from Xbox360 or PS3 may also be used to navigate game just as an option.
