This guide is bad.
I myself am a full valorous holy paladin, I can only pull 3-4 groups. If i pull anymore I will die. These mobs will always snare you and daze you even if freedom is up, it's also even more annoying to have MS on you the entire fight.
Basically at the end of each fight I'm OOM since i have to spam heal myself, even with SS up I still take a ton of damage. I cannot divine please during the fight either since MS is on me and my heals are almost useless. I cannot mana swing with seal of wisdom up since I'm heal spamming. At the end of each fight I'm drinking water to regain mana. The gold I loot basically pays for the waters i'm using to regain mana.
During my 30minutes of grinding I only got 3 greens and about 10g thats including vendoring the greys I got and a stack of frostweave cloth.
I could respec prot and throw on my prot gear which isn't that bad but I really don't see a point wasting any of my time here since the drops are so bad.
IMO people that listen to hobbs on how to make gold really suck, your listening to a guy that has been running people through SM for free since classic WoW, and making 75g an hour is legendary to him.
