Town hall 8.5 upgrades

I have been a townhall 8.5 for almost two weeks now, and I've finished my army camps, spell factory, lab, one level 6 barrack, hogs upgrading to level 5, and my archer queen is level 5. But my question is what do I do now? All I have left to upgrade for offense is dark barracks, archer queen, and troops. But, I can only do one troop at a time and farming de is slow. Once I finish my dark barracks I don't want to have idle builders (5 total) and lap upgrades are taking a long time, but don't want to upgrade my defenses yet. What should I do?

do your walls if you dont want to do other buildings

Dump it into walls or build everything except bows and become an 8.9.
