dont mess up.. tower remains a pinch. that's the name of the game any way.. doing the very most with the very least. efficiency. you cant make decisions on "what if I mess up" .. needs to be "don't mess up.. but if I do, identify the problem and do better next time." this 12/2 battle with team mates providing towers is a pretty surgical process .. they happen pretty regularly and the room for error is always very small... on both sides. the outcome is typically decided within 30 seconds of the first tower being upgraded. the farm being attacked is almost never part if the equation. and if it is part of the equation, 12 is just living on borrowed time any way
you shouldn't be needing to repair
