.. you would still need to grind a DOW or DOM character from 1-60 and honestly you can take a crafting discipline from 1-60 with very little investment (relatively) of gil. Just buy the mats, people have the grinding formula spelled out on so many sites.
I really don't think it would be as much of a problem.. or even any different than you say in the bot camp. Player camp would be something else though.. but you still would ONLY have one crafting discipline at 60 and that's pretty useless in and of itself for productivity.
I honestly don't see any threat or difference between what we have now.
