Hello,

I took a 10 month break, before BFA came out.

I had 2 million gold left on my account before I took a break, yesterday I purchased the 5 Million gold mount.
Apparently it is 4.4 Million when exalted, not sure if that is right, as mine costed 5 million as I am Not exalted lol.

I obtained 3 million without boxing. I am as of today dual boxing, not x5 like I used too, I might go back too x5, but for now it is x2.

I obtained gold by farming ore & herbs making flasks and selling.

I also did Heroic Raid BOE Trash farms and was extremely lucky with 4 BOE drops in 2 days.

Boxing x5 or less and or more will speed your gold like crazy. However I dont know how one would herb/mine x5 or more without going insane.

I have heroic raid lockout I was using and creating pug grps to come farm, keeping the group small.

Did another boe trash farm round and no-one got a boe. maybe it was nerfed, probably bad luck noidea at this stage.

Maybe that can help you
