I think people whine too much about companions. Shadowheart WAS good before last update, and if you really don't like a companion, by no means do you have to "put up" with them. I know that in most of my playthroughs, Lae will get the murderknife, but I like her this way. At least this game has someone who is written well enough for me to hate her guts.
That being said I would also like a friendly female companion, but I think we are going to get 2 edgelords instead, we will have to see. Worst case scenario: I will have more characters to kill. Always a fun thing to do in video games.
