1) Prevent clan castles from being lured out, just like heros can't be lured out. It's too easy to lure out most CCs with 2-3 troops, making them mostly useless.
2) Don't allow lightning spells to attack storages, esp dark elixr. People always attack by dropping lightning spells on DE storage. If you're saving up for an upgrade, they can easily get 400-1000 DE depending on amount in storage and spell level. The attack doesn't trigger shield, so you can conceivably lose 400-1000 multiple times with no way to defend against it. And with how long it takes to gather DE, its almost impossible to save up for any upgrades.
3) Add a "copy base" feature that allows you to copy the layout of an opponent or clanmate. Also add a "copy war layout" so if you change your base and don't like it, you can copy your war layout to use as your main layout.
4) before attacking a base, allow you to scout similar to how you scout in war. Let you check defense ranges, building levels, etc. Add a "begin attack" button in addition to the 30s timer to start attack.
