Since consumes and gold for Respec will be a big necessity what classes farm the easiest ?
I heard hunter and mage. And also rogue can pick pocket farm something in blackrock is that correct? I would assume war, pal, druid, priest have harder time farming?
All classes farm fine.
Mage have other noncombat forms of money making just selling portals and tips from water and food, not a ton but it’s just sitting in town and easy enough. Hunters have to pay for ammo for farming but can easily outfarm the costs with their speed and personal tank, not to mention selling mara runs is very profitable. A rogue can pickpocket BRD, not always as easy as they claim though, two resists to pickpocketing can get you killed but is profitable, it’s also more efficient if you’re sub so it’s harder to be caught but very safe for pvp servers.
There’s a ton of data for farming via the pserver community that have been uploaded to youtube and such, and those vids will help you get some ideas on things to do for your chosen class/classes
That being said, one thing to consider is that pserver gold farms often focused on raw gold instance farms because they had massive overcompetition for profession based things via drastically higher server populations than normal.
So there will be some differences on the gathering end that might make it more profitable (baseline metal/herbs) or less profitable (black lotus, which if memory serves was a primary flask reagent was apparently all over the place on pservers, and fairly rare in vanilla)
