In about 2 months of playing, I have almost all my classes (including hand and land jobs) maxed. In less than 2 months, I had all my combat classes maxed.

Now, that being said, it is a chore. It is work. There are a few tricks to make it go faster, but in the end, it is a rough grind.

From what I've seen, I doubt that there is much in terms of plans to change this. What you can do, however, is to only do grinds as your get bonus exp from resting in a sanctuary so that you are doing less grinding and otherwise just do your dailies and weeklies.
