Today I’m going to look at tanking cooldowns. This is not supposed to be an argument over who has the best cooldowns or who is overpowered or blah blah blah. This is a learning exercise so that everyone can better understand their tanking teams. Remember that cooldowns are not balanced in a vacuum; Blizzard takes everything into account when they balance tanks, not just your damage reduction cooldowns.
