Is there really a need for a trainer when you can use console commands? I find console commands easier than using the trainer. Not that I don't appreciate the effort that CH puts into all their trainers. Love this site.
I see your point though not everyone is familiar with console commands or how to apply character skills (setav/modav) despite not changing since TESV. CH cherrypicks the best of the bunch then we conveniently have a trainer on hand to input it for us. Only option I'm using on Survival is super carry weight because my character is weak genius
I don't have TESV installed anymore but iirc that trainer didn't use consoles commands and neither did Fallout 3 nor Fallout: New Vegas. The main change to Fallout 4 was that console commands no longer affect achievements or the old Windows Live, otherwise the console is essential for troubleshooting eg. broken quest lines.
