i dont want to call out Antilus now, i like some of his posts recently, but he said what is true (even if i disagree with some of what he said in that thread).
and this is also what i remember from the launch and fist month and believe is still a thing.
Cannot say how it is today, because i just play Heresy+, but i would bet a box of beer that a lot of people just farm Sedition/ Malice by speedrunning giving a sh!it about their team, because they can easily solo it.
Like people who are less skilled or just not able to do what others can do and do not belong into Damnation or Auric mission, players who play Auric regularily can play Sedition but then should help the team and be supportive and not too eager or they just dont belong in such easier difficulties.
It’s mostly bad gamedesign or missing limitations that People start to “exploit” low difficulties just to farm coins for Melk.
