I put together a low level Classic Warrior Tanking Guide that may be of interest to you. I’d love any feedback you would like to share.
One of the things about tanking that you’ll inevitably notice is that some groups are better than others. As you gain experience with your core tanking abilities, and keybinds, such that holding aggro becomes intuitive, you will be able to spend time to notice what each player is doing.
This can help you anticipate when you’ll need to use which skills, in order to prevent a potential wipe, but also to identify which players are doing what things that they could be doing better. In the beginning, it may seem like the common denominator is you, and it may well be, but if you give it time, and keep pushing through, you will get better, and there’s a great deal of satisfaction in leading a group as a tank.
Good luck and have fun!
