So your 22% increased armor will hold for one hit - no matter how much rage you spent on it.
Regarding high damage/ high mixed damage abilities like the Glaivecombo, nothing has changed as well. You pool for those particular attacks and get a full barrier going.
With 4p, barriers will make you pretty unkillable during ls. Especially if the situation is dire and you recived a few hard knocks.
