Well, since damage is dealt before status effects are applied, and all CC effects I can think of are loaded with quite a bit of damage, your magic armor will be quickly depleted, at which point everything stuns you. I mean, I'm going up against enemies with full magic armor meters, and they're frozen in one Hail Strike, which is an AoE.
So, armor will keep you safe from all status effects while it's up, but it gets burned through very fast. Combat is basically either you do it to them, or they'll do it to you. Or you can play 2H warriors with high initiative and just kill everyone before CC is a factor.
