Thanks again for the replies. When I found out that the xp was going to be set to zero on each level, I made sure that everything was ticked over to the next level so I didn't lose massive amounts of xp - with the exception of my crafting and gathering jobs which were already so far ahead that I could see what I could make in Stormblood - so the most I lost was maybe around 10% of a level. Since my lowest job was at 52, I put all the 50 to 53 MSQ xp on it, then when the MSQ out-leveled it I switched to the job that was at 53, then switched to PLD when the MSQ hit 54 and have been leveling it alone on the MSQ since then. I did spend two or three weeks spamming Sohm Al with my squadron to get everything else caught up, but that's the only thing I've done for xp besides the unlock quests to get flying.
