At TH8 right now.
All defences are maxed out, except for the teslas.
The majority of my walls are level 6.
I've got two more upgrades to do in the lab.
Barracks are all level 9, DBs are level 3.
Do I max out completely before moving up? Obviously my walls need doing. I expect to be able to get them all to level 7 before my teslas are done, and probably a good amount of level 8 walls too.
