Auto Brewers, like Auto Smelters, don't give you the mamma skills. That's why I hesitate to use them.
Me too. But one thing you can do to automate brewers to a certain extent is set up a water block above your brewer feeding into chests via hoppers, and then more hoppers feeding from those chests into the brewing stand. That allows you to throw empty water bottles into the water block and they fill up with water then automatically feed into the chests, which then in turn automatically feed into the brewing stands when you remove the completed potions.
So it does save a lot of time when you're brewing and allows you to semi-automate the process without losing mcmmo skills. You are welcome to check out my base where I have it set up on Valour.
Yes, I have a set of dispensers and hoppers ontop of a brewing stand containing the ingredients, and a double chest and hopper to the side containing water bottles. to brew a set of potions i just hit one button, it dispenses the ingredients in the right order and brews them. i then remove them by hand where they are automatically replaced by filled water bottles, hit button again to repeat. speeds up the process quite alot
