I don't really like it myself, mostly because of the fact that it entices the construction of a full physical or magical party, which cannot be considered as good I think by any metrics.
I would have liked an armor system that basically starts the combat by having 0 chance of CC'ing someone to giving more and more possibility. The all-or-nothing does not seem good either, so a solution like the one given by Stabbey and adding something that would be a percentage of chance depending on the percentage of armor you have would be better I think.
And to be fair, I'm not going to make an argument regarding this as we have no way of knowing, but a looooot of people put a positive review but haven't even finished the first act, so...
