I heard that engineering for one has many items that binds when picked up. Is this also true for other crafting professions? If so, which ones, and how much does it affect the transfer of crafted items between alts? Thanks.
By affecting the transfer between alts, I was more leaning towards whether there would still be useful items for my alts that binds when equipped. For example, potions, rings and gears among others.

well
some professions allow you to utilize profession-only items

most do yes that i have noticed
it is bind on pick up so means that once made you can not give it to any 1 else not even an alt
if you transfer sides hord or alliance then you will get the same thing
