I'm TH8 and it is harder for me to keep all my builders busy! Uni work, social life, girlfriend, family, football and rugby... I have other things to do than sit and play clash but I haven't lost interest and there's time for everything! As long as I can keep at least one builder busy at all times I know my base is progressing currently upgrading my air defences to level 6 and my teslas to level 4!
