One builder free at all times for walls?
I know there's advantages/disadvantages of both:
One builder free:
- Can always dump gold/elixir into walls (and even farm + dump more resources into if you don't have a shield)
BUT
- You lose value of that builder for the time that he's not hammering away at an upgrade
One builder not free (basically opposite):
- Getting most value out of that builder for always upgrading (especially if 4th or 5th builder that has been gemmed)
BUT
- Your resources have potential to stack up (thus increasing your chances of being raided if you don't have a shielf)
Or does it all depend on your TH level/farming situation/how active you are?
Personally I try to keep all builders active to get the value. I try to synchronise builders so that there's at least one that finishes sooner than the rest (e.g. 5 builders working, 1d, 2d, 3d, 4d, 5d left on buildings instead of 2d, 2d, 5d, 5d, 5d). I dump resources into walls and then start a new upgrade. A lot of my walls actually get done while my TH is upgrading (along with the few last buildings that need to be maxed)
What does everyone else do?
Never. It's a waste of time
Builders are my ♥♥♥♥♥. He has to work for me all the time. I'm not paying him 2k Gems for him to sit on his butt.
