I've not seen a casual crafter reach milestones faster than a dedicated crafter yet. I'm the only guy on my server providing purple techblades for consulars. I'm pretty sure casual crafters can't do that.
'Can' and 'if' are the words you were looking for
The point is if I want to craft a specific artifact item, I can RE forever, spending cash by trillions without getting that recipe.
It is frustrating and by no way rewarding for the crafter.
