RANGER - Metal Bullet price/craft

Hello,

I am a "sniper" and I am a bit frustrated to see the price of the Metal Rounds.

After the lvl 15, the next weapon is a GUN and so need to fire the Metal Round.

Why not make the recipe for crafting them, open to everyone instead of locking it behind a specific job ?
Replace the Ammo recipe by Wetstone, boosting the damage of weapons for the Blacksmith or something like this if you want to keep and interest for the job.
Actually, this Metal ammo problem just stack with one more problem to the jobs and classes balance.

And another thing : Techniques don't take your stuff damages in count

Thanks.
