To enter a good clan you must have many stars and people who have started 1 year ago can't have the same stars as 2 years player.
Adding the number of stars achieved during a year or a period you would know the current performance of each player in war.
Another option would be to add the number of wars in which you have participated for some time (for example, one year) along with the stars achieved.
This would help players who have started recently and also people have been unable to play for a time. Recruit good people in war would be much easier and all the players will have the same opportunities.
