So I'm currently th5, I have all of my defenses maxed. I have 1 lvl 7 barracks and the others lvl 6 and lvl 5 . Most collectors and mines are lvl 6,5 and 2 lvl 8 collector and mine. So I was wondering, do I have to upgrade EVERYTHING before moving on to th6 ? I really want to move on already because I want to get healers and upgrade more troops. Please help and thank you
