The next one is the warlock now this class has two primary
If you are thinking of taking on the role of a protection warrior WoTLK Classic Gold, they play very similarly to arms, but the stances don't change that much since you have both shields and swords available all the time and you have the majority of your skills that can be utilized in a defensive stance that is, you can be able to doze off your fellow players as well as yourself and you're clearly tankier than arms.
You do have silences and stuns, giving you decent CC and burst however you're consistent damage is pretty poor compared with arms and you also lack Mortal Strike. It is definitely a nice option for specific prompts and, if done correctly, can do well. The next one is the warlock now this class has two primary PvP specifications, which are affliction and destruction. Both have distinct playstyles so let's start out with the latter. This specialization has a ton of control. It also has many dot damages.
The affliction warlock is truly unique playstyle seeing as you are almost never focusing on one specific target. The goal is to have your unstable affliction and corruption up on the most targets you can with the proper curses while trying to stop the team that is gaining momentum by using things like curse of tongues, Curse exhaustion, fear death, labor, and so on. Also, you must be extremely mindful of the pet you consider to be keeping it alive is incredibly important.
The pet you have make magic out of you and your teammates, but be able to purge and even lock down the opposing team not to mention its ability to reduces the damage you suffer by 20 percent. The reason you should be an disease Warlock is because you like multitasking and have plenty of control to provide. You'll also be rotting people to death with your dots. Because you've left tap you also don't run out of Mana.
Why you wouldn't want to be an affliction warrior is because they are pretty squishy and the only real defense they have is their portal, which if misplaced or misused could lead to your death. Also, you shouldn't be a fan of the speck, if you don't enjoy having to concentrate on multiple things at once buy WoTLK Gold. When you were fighting a bad affliction, warlock, your whole team is going to die because no one has the ability to cast, and whenever you try to make pressure, your DPS will not only be waiting in fear, but will as well, that fear could be covered by an unstable affliction.
