You said you were waiting to get Provoke until you hit level 30 as MRD, correct? I'm of the opinion that Provoke is *the* single most important thing any tank could have, so you will make it much easier on yourself if you get it as soon as possible. It's just such a great cooldown, and it's nice to be able to practice using it before you get too ingrained in your ways of tanking without it.
