That's true about infinite yield farm but.. i think it will be better to left this "simple" in A17-A19 style. Random harversting need in my opinion more complexed system - few fertinizer types, how far it is from water some plants prefer be near water some far etc.
But... not now. If 7dtd2 will be realased it will we be cool if this will be expended.
@PinkLed5 farming is not gambling for years. We have books, algorithmes, better tools , better plaint varieties etc.
Ofc zombie outbreak make a lot of things harder but still this is not gambling - it is like you are buying a 1$ lottery ticket and you have 100% chance to get at least 2$ dollars. So you just don't know how many you will win but still you always get more (except situation like zombie destroing your farming yield.)
If this was "7dtd medival" i could agree with you but now you have enough "tools" to be effective.
