Appreciate this is an old thread, but I got very confused by this in my recent playthrough (first with DLC in a very long time) when, about 110 hours in, I finally got a skill to 100 and couldn't work out why I couldn't make it Legendary (turns out I could, but obviously the button gets hidden). Seems strange to have something in the STEP guide that doesn't actually change anything other than hiding a feature from the game. I also took a long time finding the right ini file (because somehow I ended up with one in with my saved games in Documents). I think it would be helpful to add maybe in the Baseline to switch the Legendary button back on at least? (And therefore also educate people where to find the ini file / tell them that they can tweak this to change gameplay - I use Vortex (against advice I know) so it is just in the game Data folder - don't really know how MO2 works for thing like that).
