Anyways to be honest every profession can easily farm in this game and make
guild wars 2 gold. If the player knows how to play their classes and the spots to grind/farm at. But that’s just my opinion.
If you want an easy and free ride ticket or whatever you want to call that, I would say Warrior. You could with the correct build and I do not recommend it but it’s possible, place that class everywhere and go afk. You will have hours of farming without any effort, or having to watch your hp and combo’s.
Warrior is great because if you keep upgrading armor and weapons you’ll faceroll everything in PvE. Easy to farm when you can easily beat every mob. You also provide high DPS for zerg champ farming, guaranteeing you’ll always get your share of the loot.
