Id do Lvl 10 walls till you have nothing to do with elixir. Or just finish all lvl 10. Your % is higher when you hit TH10's so take advantage of that lol.
Here is my crap base update, still working on my queen and since we can use elixir for walls... Ive begun making them pretty lol.
Still farming in champ and im putting dents in bases left and right
