Ive seen your posts.
Generally, i would think that Larian just made some quick presets so they can go on with testing and development, not that those are their best and definite builds they would so kind of support.
In that sense my suggestions are not telling Larian how to do their business better, nor they are the most perfect builds, but more of examples how presets can be made to be more imaginative and interesting - which also would push or hint to the players that there are other more interesting options.
The presets do need a few basic pure builds to make it easier on the players to create characters exactly like they want later on, and to choose more precisely what they want for the companions. As well as more interesting hybrids.
