Hi I'm currently at lvl60 almost max TH7 with only mines/collectors, dark barrack, and DE troop upgrades left. I'm planning to upgrade to TH8 soon.
1. Should I max mines/collectors (currently between lvl6-9). Do they useful in long term if I max them? I mostly get the resources from raiding.
2. Dark barrack is currently being built. Should I upgrade it and also upgrade the DE troops in lab before upgrading to TH8? This will take another few weeks and I can hardly wait to upgrade TH8 :(
Thanks!
