World of Warcraft Various Guides - The 5 best things Guides
Be prepared – While this sounds so simple, you would be amazed at the number of tanks that do not do this simple little thing. Be Prepared. What does it mean exactly though? I sum it up as all the little things like making sure you are repaired and have your tanking gear with you. It also includes things like bring food and drink (if you are a Paladin and need mana), flasks, elixirs, potions, bandages, reagents, and anything else you could possibly need. While many of the items you may not need, and probably won’t if it is a simple instance, it is always better to be safe than sorry.
Plan your pulls – Make sure that you know which creature in each pull should die first, second, third. Know which if any should be CC’ed or kited away from a group. If the pull is difficult for your group then make sure you mark them to make it clear what the order is. Have a set kill order such as Skull, X, Triangle, Square, Moon. Whatever order you decide, just make it clear.
Research – As a tank your job is almost as much out of the game as in the game. You need to learn as much as you can constantly about tanking techniques, tanking builds, boss fights, strategies, and more. As a tank you will generally be in charge of what is going on, so make sure you know enough to be able to handle it.
