This thread just reminded me of something Linsey Murdock said on the beta forums:
Linsey Murdock -
"The way leveling XP gain works in crafting is this: For leveling a discipline from 0-400, you will gain 10 levels along the way. By maxing out all 8 disciplines, you will gain 80 levels. That means you could dedicate a character to crafting, feed it all the mats you get on other characters and level it all the way to 80 without ever needing to kill a thing. As hardcore crafters, we think that is pretty cool."
So, this pose a question, do I make an crafting alt or do I try to split the crafting proffesions up on different chars?
