True, but I'm being conservative in how feasible it would be for someone unskilled to get around to covering a missing resource in the crafting areas, since we don't know a lot about the XP mechanics. 

Like I assume there's a base number that scales in proportion to your tier and the type of activity which is then fed to the multiplier that's based if it's a primary or secondary role.

Everything would provide a set amount of exp.  Like a Tier I creature and Tier I ore might both provide a similar amount of exp, so both help you with leveling up stat wise, but when it comes to Role exp you need to decide what activity you want to do be it combat, gathering, or what have you.
