Simple suggestion – Instead of attacking with those troops you have in your army camp, it would be nice if you could decide what to bring so that depending on the base your friend posts, you can decide what you think is the best combination of troops and spells. Also you may add customised troops so that you don't have to decide each troop each time.
Furthermore, I totally understand the reason why you don't want to make available heroes in clan wars when they are upgrading, but what's the point of not having them in friendly battles as well?
I hope you find these ideas interesting,
Alex
