Sorry if my shorthand was unclear. On my main account I have the 8 classes I like to play. I have 4 alt accounts, each with 2 level 50s, 1 also have a level 49 HK that I haven't felt like finishing yet.
What I do: Log in alt account 1. Do my 3 dailies (6ish minutes). Work on my weeklies, usually 1 boss rush (i forget what its called exactly) just kill the first boss, that weekly is done (less than 1 minute). 2 guardian runs. Kill weakest guardian (the bear), need 6 "souls" for the weekly, they usually drop 1 each time and you can only collect 2 souls per day, but there's a system where for every soul you don't collect per day you get half a bar, 5 bars max of "double loot". I bar, 1 kill, 2 souls drop. 30 seconds per kill. Then I spend my labor points gathering. Mining is about 15 minutes, with ok gold. Fishing is like 30 minutes, but like 3x gold. Depends on how much time I feel like spending that day.
Objective is to earn 72 Epona points each week, which earn you Epona Badges (amount you get per point goes up with gear level). You trade the badges to a vendor for a bag with gold in it. 80 badges = 200 gold. 200 badges = 500 gold. 500 badges = 1200 gold. Each bag also has a chance to drop gold plates. Light plates are worth 100g, Heavy are 1000g, and the last one is worth 10k and really rare. Usually get a few light plates total every week, plus the occasional heavy.
Each daily is worth 2 Epona points, each weekly is worth 12. Maximum Epona that can be earned from dailies is 18 per day. No max on weeklies. So, with 2 level 50s per alt account, I can get my Epona gold bag on day 2, then all I have to do is log in and spend my labor points, til weekly reset.
With my current gear score I get like 715 Epona Badges per week. Which is 1 1200g bag and 1 500g. And I've been fishing, though it puts me to sleep. Pearls that you get from fishing, currently sell 40g for a stack of 10. I get like 80-110 per account per day.
So, long story short, 5 accounts, spending around 45 minutes a day per account for the first 2 days, and 30 minutes the other 5 days, nets me around 24k gold, give or take. Nearly 5x more than a normal "free" player can earn. "Nearly" because there's a couple things I don't bother with that give gold, like weekly dungeons, or some ocean "adventures" shit. I'm just looking to make gold quickly and efficiently.
