Odd Question re: starting class

[Enkidoh]

Well, as your join date is 2011, that means you're almost definitely a 1.0 player, hence if you're interested in finding out what class you started as back in 1.0, still on your Lodestone profile, on it's main page, click 'Sixth Astral Era' button, and look through the list of 1.0 Lodestone achievements (you can actually do this even if you're not logged in, depending on your privacy settings) - it will include any levelling you did in 1.0, and hence whatever was the class you first gained exp in, would have been the class you probably started 1.0 as.

EDIT: hmm, after checking your Lodestone page, it seems you don't have 'Sixth Astral Era' button listed on your profile, as shown here on my character's Lodestone profile (whom I transferred from 1.0) - did you start from scratch on ARR's launch instead of transferring your 1.0 character? If so, disregard my previous comments, as they're only useful for a character transferred into the game from 1.0 and hence, is not relevant to a new character. Ah well.
