thank you for detailed information. Not that I dont believe you or anything but I though that automax level blocks the chance to get 2 points into a stat per level reached (sometimes thrall gets 2 points, sometimes one and sometimes nothing when he gets level)
My source is a video from Wak4863 on youtube: https://www.youtube.com/watch?v=Q_TtqcWXqeo
In this vid he did a research about this issue and he doesnt recommend to automax thralls because they get less points than thrall leveled normaly.
So my conclusion based on this video was not to autolevel thralls if I want them to be as good as possible.
