Not going to read this whole thread, but if ALGs were removed, everyone would just save up all their SP, train everything to about 30-40, then spend all their SP for that attribute at once. It'd be like slow building on steroids.
Also, archetypes make ALGs more in line with how players want to build. For someone worried about competition at the lower leagues, I'm surprised the OP doesn't see archetypes as a good thing. Instead of waiting until level 40 to add agility to a safety or waiting until level 50 to add strength to a WR or speed to an OL, agents with archetypes can train up the attributes they want from the get go.
