I'll be leveling everything to 70 regardless (I've already capped everything to 60), but I definitely want to do Rdm first because I am exceptionally curious as to what exactly it's storyline is and to learn more about the lore. I'll be going drk main in to SB to take to 70 first followed by my main dps class (nin) second and from there dabble in the other classes over time between leveling my gatherers and my crafters.
