U will find this a common problem once u decided to raid for ur walls. Or when you
are almost maxed out at ur townhall level.
you have 3 option now
1. Donate dragons
2. Raid bases with lesser elixir than gold , example : raid bases with 200k gold and 60k elixir . About this ratio
, then you wont feel like you are wasting elixirs
3. Theres nothing else you can do beside wasting more of it .
