Both Red Mage and Samurai will have their initial job quests in Ul’dah, so if you logged out in that city, you get full marks for prediction. The next part of the Main Scenario will start in the Rising Stones, and players will want to stop by Revenant’s Toll anyhow to exchange all Heavensward tomestones for Allagan Tomestones of Poetics, which now serve as the all-purpose stones for prior expansions. This also means changes to the roulette structure, changes to the UI, and… well, the point is that there are a lot of changes. Luckily, you have all day to read through the notes before the game comes back online tomorrow.
