Best Solo Profession for a gold grinding addict?

I just bought GW2 and HoT and am wondering what the best profession is for a fresh account for someone who loves grinding and mainly plays MMOs for the economy and becoming rich. By "addict" I mean that I have no issue grinding for gold in 6-12 hour nonstop sessions (I come from Korean MMOs where this is even considered casual).

It seems like people have said Necro, Warrior, Guardian, and Ranger... but almost all of the posts I've found are from 6 months to a year ago and I'm not sure if any balance changes nerfed any of them, and I don't want to blow my free 80 boost on a profession that isn't S-Tier for solo grinding.
