I enjoyed being Samurai in XI, so i hope for some Katanas to enter the item list.

As for other classes i'd like the Corsairs with a large variety of weaponry. Rifles, guns of all sorts as long as they are FF'ish.
I'd like to see a class using the gunblade and summoner, pet class, Red mage, puppetmaster, the more classes implemented the better imo, as long as it is all well balanced.
