I'm pretty sure this idea will be rejected but I have to try anyways. I'm a almost maxed TH9. All my elixer troops are fully upgraded and i have nothing to spend elixer on but L9 walls. I have plenty more L7 walls then L8 and L9 combined due to poor base advancement on my part. I am requesting that SC would bring back the ability to upgrade L7 walls with elixer for TH9 and up.
