I don't like making the stuff at low level because most of it, in my personal opinion of course, looks boring. it's exciting to make things at high levels because they look neat and do neat things. The actual process of crafting has been dissected to the point of tedium. There are optimal rotations and gear you can just google. I like what I can make, not how I can make it.
Everything in the game is "content". If you mean that the beginning is supposed to be boring I can't really say one way or another since I didn't make it, but I would like to have a shortcut NOT to engage in that part.
To a degree there is no way we can argue the effect, because we can't see the future..
But people have been saying the cross server visits were going to destroy individual economies as well.. and that hasn't happened either.
The Optimal way to do anything for fun is the one that's the most entertaining. If you find mindless grinding rewarding and fun then more power to you, but I doubt that allowing a shortcut in crafting will do anymore than the current culture of mobile gaming already has.
