I would settle for a number on their profile. War attacks not used: X
No, and that's why you don't bring random people from global to war, have them wait 1-2 wars before you put them in and make sure they share a war attack strategy to see if they are good, then you can let them join.
Your clan should be good enough to handle 1 or 2 deserters. If not, your clan has more issues than you think.

It's not only new people. I have been in clans where long time members decide to up and leave for whatever reason and do it in the middle of a war. One person leaving makes a difference. There should be some sort of penalty. I like the idea mentioned about a number in the profile saying "War attacks not used".
the only problem is that there are plenty of valid reasons for missing attacks, hospitalization, a funeral, power outage etc. etc. I'd hate to have a blemish on my profile just because I couldn't attack because I had an emergency.
Now if you could rig it to detect and show war attacks missed because you weren't in the clan on battle day I'd be up for that.
