They aint jerks. If you roleplay as a Lawful Good character they appear as such. If you roleplay something else, they aint jerks at all. I think the companions in EA are very well written, are close to 5e lore and are super fun to adventure with. The animations, early as they are, still help convey a lot of what the characters are about. I think the finished product will be incredible regarding companions. This is likely the first time I've seen compelling and understandable evil companions in an RPG. They are really superb.
