I have 2 high level players, so i can create a Death Knight. I am certain to keep him as a main hereafter. But i want some advice on two seperate matters. Feel free to provide any hint of helpful insight, since i am still learning.

1) Shall i roll a Human or an Orc? Do not advice for another race and/or against those two of my choice, i strictly want one of those. For many reasons, among others game lore and nice looks. Which one of them is better suited to choose this class?

2) Supposing i can have any materials i want (specifically minerals and herbs), what proffession combo is best for Death Knight? Shall i go for...
a) Blacksmithing/Jewelcrafting?
OR
b) Alchemy/Inscription?
Once again, please do not advice for another proffession/profession combo, or against those that appeal to me. Simply tell me if you would have your Death Knight learn a) or b), and for what reasons to prefer one and abolish the other choice.

Thanks in advance, my previous question was nicely worked around, please feel free to keep up the good work! Cheers!
