I have to admit that I'm really sick and tired of the existing tome system. This will be the fourth year of grinding the same job. Palace of the Dead was a good idea, but the XP really needs to be boosted. Other MMOs add a massive amount of XP to old content because it's boring, and people don't want to play it over and over. In FFXIV, it's exponentially worse because now we have a TON of jobs to grind. But the only thing this accomplishes is having an alt job to queue and do the same thing over and over. I think people are just getting tired of maxing out all of the jobs because there is no major incentive to them.

The real failure here is the inability to realize that people are tired of grinding dungeons.

Palace of the Dead doesn't teach you how to play your job, it gives you the basics. So increase the XP significantly so people can get to 70 and start learning how it works.
