Within the MSQ I was able to get 2 jobs to 100 and likely could have gotten a 3rd there if I put off the MSQ for another day or 2. I actually think this is a good thing for those of us who like to have the option to play more jobs at max level.

I remember having to grind fates and side quests in ARR to level so I could do some MSQ quests. I think that is one time I quit the game since the XP for these was so abysmal I couldn't imagine doing them for 5 levels.
