I agree with everyone that the underlying issue is the levels in which every job, not even just tanks, learns skills is pretty messed up and needs to be looked at again. I think it honestly makes it harder to learn how to play a tank when you don't get your most important mitigation abilities until way later in the leveling process. At the very least, tanks should get a weaker version of them at lower levels in ARR and use traits to buff them at higher levels similar to what happens at level 82 so that newer tanks can learn how to use short CD mitigations earlier and have more time to practice and get better at it.
