Becouse most of then never reach act 3 or the ending.. thats why things are this way yet.
(things are actually getting a turn to worse pretty fast, Bunch of People are hating Halsin and Karlach even more with evry patch they release, same is happening with the Hero ending.. evry day has a new post here or in Reddit talking about it..)
And Please admins im not saying that this situation its any fan foult.. this is Only Larian to Blame ok.. im not stupid, they have nothing to do with this situation that larian is creating.. (its like i said before.. its the same when yu love someone and they dont give a F. for yu.. and only care for others needs.)
Just Secconds ago Popped another one Hating Karlach becouse she broke the Romance with Minthara.. get it what im saying ?! they are making the situation just worse for this characters for real.
