I like the hardcore difficulity of this game, but frankly, when trying a new build and after discovering that you picked up some useless feat or put skill points into some useless attributes, going through those outpost quests again and again is simply tedious. This game doesn't offer that much freedom in the first phases that adventuring would keep up interest in trying out (and failing) different builds, so what I'm suggesting is that either
-Add a once-in-a-game opportunity to revamp yuor character after returning from the Junkyard, as you probably know by then what you've done wrong in the character build.
OR
-Add a semi-hidden cheat menu that allows you to alter your character build, but not to make it too powerful so that you can't gain levels or acquire extra equipment. Using this could have a slight punishment for the player like changing your profile picture into something goofy, so that hardcore players still feel better people for not cheating.
