I'm torn here:
On the one hand, I agree entirely that fate/dungeon/level/hunting log grinding is boring, especially in a game where the endgame (level 50, after the main story) is considered the most important/entertaining/most-focused-on part, and that the story quests are the best source of exp in the game.
On the other hand, this would make the game soooooooo much easier, what with leveling your remaining classes being a big time-consuming part of the gameplay. Without it, people would be rushing to 50 on all there classes (I think even crafting and harvesting) and light speed (or at least faster then they are now. which, depending on how serious someone takes this game, could already be really fast) and would get bored, especially with the game still in 2.1 going to 2.2. We already have an unhealthy amount of the community that are like this without having to redo the story and an even bigger amount complaining that the end-game is a grind-fest for tomes and extreme mode accessories. :B
