Suggestion:
In a war right now we have 5* as max that can be got from an attack. I suggest that you expand this to 6* with the additional one for 90% destruction.
Reasoning: There is a huge difference between 75% destruction and 100% destruction. It is possible to get a 3* easily on tough bases and with troop cards/bombers to 75% destruction. But only a skilled player can go beyond that. An incremental * would help the good defenders as well skilled attackers gain more bang for their effort.
