When looking at "My Clan" in war menu, I think it would be nice to be able to see how many stars each member has won by attacking and also how many they have given up to opposing clan. This stat could reset every season along with the donations given / received, attacks won and defenses lost info. This would enable you to, at a glance, evaluate things like whether or not a certain base design is working well or who may need to be kicked for poor overall war performance. I see no downside... other than maybe some people getting embarrassed at their running log of failure. But this is also why the stat could reset every season, thus giving you a "fresh start" if you will. Also, it would make the start of a new season the perfect time to overhaul your base so as to get a good solid 14 days/7 wars worth of defense data.

PS... I looked for similar topics in the ruled out sticky and didn't find this idea, but I'm sorry if i missed it.
