Not sure if this should be a suggestion or if it's regarded as a problem? I've just fought a battle in which everything was destroyed except the PH (I run out of time with the PH itself being 50% destroyed). I was told the base was 77% destroyed and I was only awarded 1 star! I know that the PH is high value, but this was a large base and only having the PH left standing should at least give 2 stars.
