Guild Wars 2

So this idea just occurred to me so I haven’t thought it out fully yet ( or checked if there was a duplicate topic… I probably should have, in retrospect, but I’ve already finished typing this post. ), but I was thinking that a possible way to make crafted goods more desirable ( currently, except for some end game stuff, crafted goods sell for less than what it takes to make them ) would be to add branches, or specializations that one can go into, and are committed to. I know that a big premise of guildwars 2 is that everything is openly accessible, but I don’t think that this would cripple those ideals too much, and could potentially make crafting more desirable an investment, aside from gaining the achievements/titles.
