Malkorok and Varian... no. If you don't pull those cards, don't go out of your way to craft them. They are not worth it.
I agree. Malkorok and Varian will eventually rotate out but Rag is in the core set. That's where I try to craft the most stuff I need. I would look for a different warrior deck.

I have exactly 4800 dust for Ragnaros , Malkorok and Varian :) but im not sure about it
Ragnaros, yes.

prioritize 'classic' cards first...
Cairne Bloodhoof, Sylvanas Windrunner, Ragnaros the Firelord, etc... should be good in a long time investment... :)
