Just a couple of questions:
1. If I have 1 - for example - DK, can I do the questline for all 3 artifact weapons with it?
2. If so, is it available right away or becomes unlockable as expansion progresses?
3. And finally... Let say the DK I have is Unholy - i.e. uses a two-hander. I do the questline for him and then I want to aquire the Frost artifact (i.e. two one-handers). Can I do this questline playing as Unholy (i.e. still using a two-hander) or is it required for me to change spec and play through the Frost questline as Frost (i.e. use double one-handers, because some abilities won't work with a 2-hander)?
4. If I play a class that has an off-hand - I read somewhere that I will get a suitable off-hand too. Is it true? Do you get it with an artifact or do you need to do some extra content for it?
