I've been Town Hall 9 for a few months now and it's come to the point where I have nothing left to upgrade that costs elixir and I'm unsure what to do with it now.

I've had people suggest all dragon raids, which would be fine, but they take far too long to train for my liking and I still need gold for various defenses and walls. I've been doing overnight dragon raids, but that still doesn't do much for me - I'm still gaining more than I'm losing.

Would it be better to just keep doing all dragon raids or stick my elixir storages outside walls? What do some of you do with your elixir when you don't need it?
