Upgrade walls with elixer.
If somebody already posted this idea my apologies.
I think walls should be upgraded using the players choice of either gold or elixer. It will cost the same amount of either to upgrade a wall. How it will be done is when you click upgrade on a wall and it takes you to the screen where you confirm upgrade instead of one box for gold there will be two one for gold and one for elixer.
The reason i think this is a good idea is twofold. One because it will make walls a little bit easier to upgrade, whiich i think is necassary because they just take too long right now and 2.) because it will give us a quick way to ditch some elixer. Usually when i upg a ton of walls it is because all my builders are building and i dont want to have a ton of gold in storage so i dump it on walls. There is not really a way to do that with elixer tho so i think this would be a good way.
