The fact that a BB can take a hit is factored into it’s cost, so it is expected that you would soak up hits with it’s ability. Remember, you paid for that when you purchased it. If you think about it like that then it is sort of like suggesting that it is bad form to hit on a 4 when you attack with a bomber, and reducing it to 3.
If you are playing with new players and are worried that they forgot about this ability and didn’t factor it into their attack plans then I would just remind them before the battle and allow them to adjust their plans if needed.
