If I ask a child if he wants to eat candy everyday, or eat his healthy food everyday and then get his desert. I think you can figure out what the child will pick. Even in the case of adults we usually pick the "Easier and more "Pleasing" route without thinking of the long term consequences.
Really depends on how they were raised.

I have the perfect example; my two aunts. One of them has children who only eat chocolate. The other has sons of the same age group who make positive health choices even when their mothers aren't around. It all comes back to how they were raised and personal choices.

The current grind is Materia wether people want to beleive it or not it's the defacto way to improve your character once you hit the level cap, a fully materiad player is leaps and bounds better than a vanilla rank 50. It seems to be a matter of visibillity for some, it's less noticable when it's not something you can gague with a number like the class levels.
This has been my point all along. The current rate of exp allows for a much more personal "journey."

A player can rush a single class to 50 and play events with friends. Or someone can take their time to level multiple classes to 50 and then multiple materia on gear. As long as multi-materia multi 50 > multi 50 > multi-materia single 50 > single materia all should be right in the world.

The current rate of exp will take a casual player just short of three months. If someone is going to take the time to have the best character possible before stepping foot in an event (including crafts and DoLs) it could take years.

That's why the current rate is just fine with me. It really comes down to personal choice, and that's the way it should be.
