Mobs out in the open world generally have higher movement speed and higher attack speed than you. If you were to stand still and trade hits with a mob back and forth you may end up trading 1 of your Auto attacks for 2+ of theirs. If executed properly, The Hamstring Method allows you to trade 1 hit for 1 hit with a target, drastically reducing your damage taken while not reducing your damage at all since you are monitoring your natural auto attacks with the swing timer.

14 Nov Will I gimp my raid by playing Shadow Priest? I have a burning passion for shadow priest in vanilla and I mostly want to raid. I've been talking to some people I know and some of them say that they would never bring a shadow priest into raid and others say that they absolutely want 1 shadow priest in their raid group. Why the mixed reactions? From my understanding, shadow priests in classic are mainly brought to raids to buff the damage output of your warlocks with Shadow Weaving. How many warlocks would a raid need to make 1 shadow priest worth bringing over a mage for example, and am I gimping the raids DPS by taking up that raid spot?Luminé39 14 Nov
That's not to say that everyone has an unrealistic vision of what vanilla WoW was like. There were already plenty of people on the WoW Classic forums pointing out that perceived bugs are just recreations of the original game. And as noted before, a flaw to one player is a key component of the original positive experience to another. WoW Classic will surely please plenty of purists in spades. But this goes to show that it won't be for everyone who has fond memories of the game circa 2006.
