Most of Youtubers have a "click-bait" titles, just put a big gold per hour in tittle and people will watch or they just farm for 15min get a lucky epic drop and say its 300k per hour or stuff like that.

Im actualling making more now when I started using low pop realm to cross realm with .. on my realm Draenor there is just wayyy to many farming bots. Its like a train and it never stops. The realm Im currently farming sometimes has 1-2 and these arent from that server but also cross-realmed from others.

Still .. prices of herbs are dropping, I mainly farm Fjarnskaggl which was like 30-32g a week ago .. now its 20-22g each, which lowers profit by a lot.

Best result I had so far was 200-230k in 1 hour farm in the morning, I was only person farming at that time, I have got on each char 700 of Fjarnskaggl so that is 7000 in hour + blood of sargeras + 35 Fjarnskaggl seeds + Yseralline seed so yeah that got me over 200k made in an hour, but on average I get around 500 herbs per character. Which gives 150k+ easy

It all depend on the realm you are farming, also when you go solo herbing its faster because as you know your toons sometimes gets stuck on a rock or tree or other stuff. I still belive that 60k per hour with single char at the moment its bullshit. Yes you could get that amount at start of expansion but no way you can get it right now.
