Guild Wars 2

Not quite sure where to put this as its more a npc suggestion.

ive been increasingly thinking about this but why is it that there are so many karma merchants all selling the same 4 items, like garlic or basil, stuff like that i forget then names but can we get some more variety from them?

why those 4 ingredients always?
whats the thinking behind it?
why was the decision to make those specifically karma?

Maybe they have a vampire problem… that would explain the garlic anyway.

Yeah I have always wondered if they intended to have them sell different things but then removed a lot of it because sometimes there are karma merchants in really strange places, like why would I travel all the way here to buy the same stuff I can get off several merchants in Lions Arch.
