I do get that there is an explanation as to why Wyll has less content than the rest of the companions. What I still cannot wrap my head around is why adding more is apparently impossible.
And I also know Larian said no more patches with more content after patch 8... But I also have seen them listening to the community before, if the community was persistent enough.
I took Wyll around this playthrough and while I actually don't mind him being "boring" I just wish there was more content to do with him. Small things, to make him more alive and bring him in line with rest of the companions.
