The city Ishgard will be 100% full on day 1 (like Gold Saucer was at 2.51 start). I also think that you have to do first some MSQ in Ishgard before the way to the first Heavensward field zone (Western Coerthas) get unlocked.
I plan to do the MSQ with MNK and BTN at the same time. Doing the fights with MNK, pick up the quest rewards as BTN for the exp. Hmm, or as WVR instead of BTN.
