What im trying to say here is that if Larian refuses to allow us to play with 6, they need to loose rules a little, since otherwise half companions remain unused forewer, since they dont fit to any specialized role.
More or less an example of what Swen meant when he said "...because it is a videogame, and D&D was made to play as a tabletop game. So for the things that didn’t work, we came up with solutions."
