I fought them for the first time today, I found a rock that if you stand directly in the middle of it they can't jump up to you so they just stand angrly and do nothing since they have no ranged attacks...
This sounds like they will fix this soon, this way of killing them sounds exactly like a bug.
It mostly has to do with the fact that Minotaurs can't jump to an occupied space, and if they don't have the space to jump they stand there thinking about it. I did find two other locations where you can do the same thing so unless they redesign the map, change the minotaurs to be a smaller size, or redsign the jumping function I doubt it will truly be fixed.
