Before everybody starts flaming me, I have a 375 Eng 70 Hunter... ENG is Extremely expensive profession also.

I am Starting a BS Pally (LvL 17 currently)I read the arguments between Armorsmith/ Weaponsmith and goin the Weaponsmith route... 

Once you take Weaponsmithing.. How do you gain your specialization between Hammer/Axe/Sword?

I'm most likely taking macesmith anyway since i'm going the Pally route....
