So when I got my acct back from my bro like a month ago, I realized that the new upgrade max is lvl 12, which I don't have any pumps or mines maxed now. On the other hand, I am working on other defensive upgrades (mainly wiz towers and teslas). I only have 3 builders, so I kind of ran into a wall because those new pump upgrades cost a LOT! So should I do 1 pump and 1 defense at a time or what?
