Both my heroes and all my dark troops/spells are maxed and have no use for dark elixir. It'd be great if we could upgrade walls to level 10 and 11 using dark elixir. I don't see how it wouldn't make sense given that you can now use elixir for wall upgrades. I searched to see if someone has already posted on this and didn't see anything, so apologize if I'm duplicating.
