How many Builders should we have :)

How many builders should we have ATM i have 3 builders with a TH lvl 8

1- Builder
2- Builders
3- Builders
4- Builders
5- Builders

obviously 5

You should have at least 4 builder but if your hardcore like most people you'll want to get 5 as most hardcore farmers and players in general do

What if we had an infinite amount?

for the peasants like me: 2 foreverrrr
for the rich: 5

I have 4 and it's fine, unless I get a bucketload of gems for free i won't be buying 5th anytime soon
