I'm a th9 who emphasizes on getting a fully maxed base before moving up townhall level. As a current th9 my concern is that I will max either Heros to 30 or walls to L10 first, and whichever gets maxed first will leave me with either an abundance of gold/elixir, or dark elixir. I would like to know how I should gbe upgrading them so they finish at around the same time so I do not waste resources when I am near maxed!
