I am thinking something that has been discussed but not given much attention.
Warband wide professions.
Technically it has been done with Blacksmithing and Jewelcrafting in Diablo 3.
So, you learn the recipes ONCE and u can use them with any character.
When someone crafts something will use the warnand skill. Specialization thus will be also account wide. Also in warband, will be a different warband bank category slot that is the regents tab similar to the personal tab,
When we will get the Houses, that will be a good opportunity to introduce this account wide proffession. You go to your House, and you use your professions
