No, no! This is wrong! Rampart and shadow skin can be used by themselves and are reliable. Raw intuition must be used with awareness when tanking trash, and at that you have to be positioned to get the mitigation (you won't mitigate everything), and you always face a 5 second window where awareness won't cover you and you will take increased damage because mobs will inevitably attack your flank. What kind of tank skill makes you take increased damage?
