I want Minthara and Halsin together in the group, I have nothing against the “genocide”, but Halsin does (Wyll and Karlach too). We lose three companions just for one. That's not worth it.
If you don't think it's worth then don't do it. I personally don't recruit all the companions simply because I don't like them. That's my choice. If you don't want to lose 3 companions because you choose to kill a bunch of Tieflings and Druids. That's your choice. I don't why they have to change it just so you don't have face the fall out of it.
