I know it may be too early for that, but starting bosses can be a great introduction to both CC/breakbar and dodges. Just give them a break bar and scatter some rocks/sticks/cogs around. Each of the first instance bosses have a big CC attack, just make it a danger circle like in raids.
In the past we actually removed teaching of that kind for the downed system because we found that throwing mechanic tutorials like that at new players so early is not actually effective and it can be a turn off because there is so much to learn about the game.
