Hi, I'm not sure if this has been suggested or not but here it goes:
I hate it when I have to wait hours or days before being able to upgrade walls. Some people may say that you have to keep 1 builder idle at all times but what if the TH has just been upgraded and there is so much to upgrade? It doesn't make sense to me why traps can be built without a builder but a wall needs one. Both of them do not need time right?
All opinions welcome. Thanks!
