I don't really like this at all. I am one of those people who wants to level up their job as soon as possible and do new content dungeons for tomes and raid for gear. When FFXI raised the level cap above 75, I had 5 jobs to the new cap on the first day. I do not find it hard to level cap jobs in a mmo.

With not releasing raids or the new dungeons for new tomestones until 2 weeks after. They choosing for me what content I will do which will then be to level up all my jobs/crafts to 60 and the new jobs before doing anything else. I rather level up my PLD first focus on that gear it up with new content rather then doing a bunch of leveling grinding for jobs I won't really play much at all.

Blizzard did the exact same thing for their last 2 expansions MoP and WoD, delayed the raids for a couple weeks a lot of hard core players were not happy with this because they sat around leveling alts while waiting the few weeks for the raids to unlock so I don't know why SE is doing it.
