Hello!

So I've been feeding the wasteland minions, hoping one would follow me home...so far I've fed 130 or so. So my question is; do minions ever follow you home? Is it a really low drop rate?

I don't know what the rate is exactly but it is extremely low; I've fed over 5k and don't believe I've freed even 20. It's a matter of luck of course but feeding minions in the Wasteland just to try freeing some isn't worth nonetheless.

oh wow it's very low! But I was expecting as much, thank you for the great response!

Of course you can still feed them for the achievements if you want, but yeah trying to feed them just to free them and take them home is a futile effort. At least most of the foods they ask for are pretty cheap.
