The whole point of crafting being the way it is in this game is because you can actually play the entire game without fighting! No other MMO, to my knowledge does this. In other MMOs you need to level up your main battle class to find the higher lvl nodes or what have you, or else you will die from high lvl monsters.
This game allows people who love to craft do exactly that. I agree that when you are crafting it does get a bit boring if it is not a difficult synth, but I think this system is much more interactive than any I've seen. And what crafting doesn't get a bit boring. One thing I would like to see, however, is being able to bring the DoH classes into battle to increase drop rates of some sort. Another example would be a Leatherworker procuring hides from a defeated enemy.
