Today had the same issue on a realm, brand new iron gear, protection 1 on every piece. Game version 1.2.5. Got one shot by a blaze not just once, but three times! Each time was with a new set of armor, because every piece of the set before it was completely destroyed each time, except for one chest plate that had the lowest durability sprite (the bar that fades from green was empty). All my other items were fine.
