"- The hero is allowed to choose one main and one collecting profession, but he can change them whenever he wants to. However, should he change his profession, he automatically loses all his crafting points and masteries."
Maybe better is to let choose for players take 2 profession's no matter what kind of? People are different, some of us don't like made some things, but some of us don't like to go somewhere and try to collect resources, in both case's people, who will chose 2 professions of one kind - they will have to buy goods or armor/jewellery in auction house, but we will have simple choise about our 2 professions, do we want to be a true resource collector or maybe we wanna be true blacksmith master, who can made armor and weapon of all kinds.
Don't hit me overmuch..
