Don't we have honour board in guild tab already?
Squad max power, total stars, total power and coli/pit ratings.
I think what you mean is detailed personal statistics which would be really nice to have indeed.
What we need is new achievements - kill 10-25-50 temple titans overall or in in 1 week are great achievements for example and you can have some rewards too. And the best part is that the achievement system is already in place.
